Does the primary chain have to be more difficult - or at least as difficult - as the merged ones? Or could someone use some private chain no one else even knows about as primary and all the known chains as child chains?

It does not need to be more difficult. You can merge mine i0coin or ixcoin right now as the primary with namecoin as the auxiliary even though those coins have a lower difficulty for example. You are correct that someone can use a private chain as the primary, one that no one knows about. For a pool though I suspect most people are interested in merge mining with bitcoins and that can only be a primary chain so 'pools mining hidden chains' probably won't be an issue.

Merge mining leaves a signature in the coinbase transaction.  A PPS pool which declares no blocks might be able to get away with it but no proportional pool could.
Yes but if a pool advertises it is merge mining 3 coins, but is actually mining 4 then it will hard for people to notice there's a 4th one there since there is a signature in the coinbase transaction for the others. They'd have to try and match up that signature with all known merged coins. A pool could even merge mine on a primary chain it doesn't advertise. Say, merge mine ixcoin, namecoin and i0coin with an unknown primary chain (a new one, devcoin, or some other). I don't know how users could track down what primary chain the pool is using.

Like I said if the pool is PPS then it doesn't need to advertise blocks so that is always an option.  Then again in a PPS pool you are simply being paid a contracted rate per share.  Who cares what the pool does w/ the hashing power.  Technically someone could open a PPS merged mining pool which gives you an option of payout currencies.  Totally hypothetical numbers:
1 BTC per 1,028,000 shares
1 NMC per 90,826 shares
1 IOcoin per 4,284 shares
or hybrid where pool pays out all 3 maybe even letting the miner set the % (i.e. 50% BTC, 25% NMC, 25% IOcoin).

In that case there is no deception.  The pool is simply paying you a set rate per share.  You can accept the offer or decline it.

The only "cheating" would be a pool which claims to be proportional and keeping part of the reward (hidding merged chains) to itself but that is very easily detected.  Any proportional based pool is going to need to provide records of the blocks it mines and catching the pool is trivially easy.  Remember the pool sends the block header to each miner on each getwork.  If the getworks don't match the blocks reported by the pool well it isn't going to be long before pool's hashing power goes to zero (regardless of the reason).  If a proportional pool refuses to provide records of blocks found it isn't going to survive either.

Merged mining will be an option in about 9 hours,

But who will offer it ? That is the question of the day Wink

Read here in a couple of threads that coinotron is testing at this moment and doublec at the bitparking said he wants to do it so there is a couple of pools to keep eye on for it.

Bitparking has always been my alt-chain pool of choice... except for that weird period of time when I was getting significantly less coins than with other pools.  I believe Smoothie was having the same problem too, but we never really came to a resolution on it.  Coinotron is also a really awesome pool for the auto mining feature but that's going to be less of a factor now with MM with multiple chains at once.

Block 160,000 passed so merge mining on i0coin is now possible.

Just want to take a moment to shout out to coinotron and bitparking (doublec).  Thanks for your contributions to the pool community!

Also, doublec has a merged mining pool up for btc/nmc/i0c

Happy mining!

We just need hashing power for there to be a level of security first.  Give it some time.

Some users on MasterPool showed interest for i0coin support (https://www.masterpool.eu/jumble/comment/71). ATM I'm catching up with the latest news on i0coin. My biggest problem ATM is that I'd like to testdrive merged mining with i0coin as AUX chain but I'm unable to bootstrap on testnet and thus can't fire up alpha.masterpool.eu with i0coin support. Neither DNS nor IRC seed seems to be working  Sad

@doublec: Didn't have a look at the sources. I remember vinced reduced the number of possible randomized IRC channel names for bootstrapping on namecoin. Perhaps we have a similar problem with i0coind. The number of possible IRC channels might be too much for a few nodes on testnet.

Does anybody remember what Ix and I0 were trading for before the exchanges stopped for them?

I don't bother with 'official' testnets. I create my own isolated test networks by not connecting to irc, dns, etc and manually bring up nodes connected to each other. It makes it easier to control.

Thank you for your feedback. Can anybody confirm if or if not there is an "official" testnet for i0coin? If yes could you please provide IP addresses of seed nodes? Would be greatly appreciated.

The bitparking merged mining pool solved its first bitcoin and namecoin blocks recently so I can confirm that merge mining of the three chains (bitcoin, namecoin and i0coin) are working on the live networks. It worked in testing of course but it's nice to get confirmation that it works 'for real'.

I've released source and binaries for v32509 of i0coin. The only change is a checkpoint added at block 161,000 to give a checkpoint past the merged mining switch on point. Downloads are at http://i0coin.bitparking.com.

When is the new i0coin logo going to be used for the client?
Still don't see it.

And also maybe put it on http://i0coin.bitparking.com/
As every currency has its coin on its home page.
This should have its as well.

And this coin is well made, put it to good use.
I want to see more of it used.

I'm working on it (for the client). I suck at graphics and am having issues. If anyone wants to prepare a patch it'd be much appreciated!
