Thanks for the replies to my previous question. I have another question that I can't seem to find an answer to. If I'm running a p2pool node, and it dies for some reason, do we lose all the work that went into the partial p2pool share?

There are no partial shares. Either a hash meets the difficulty requirement, or it doesn't. The shares the miner reports back that are lower difficulty is just for the graphs and so you can know the pool is working by estimating the miner's hash rate. But those aren't shares in terms of the PPLNS payment system. Real shares (that pay out) are reported immediately to the rest of the p2pool network to go onto the share chain, and then are paid on all blocks found until that share is too old.

All work miners do is meaningless in terms of getting paid until they find a share with a high enough difficulty to make it onto the share chain. "Normal" pools add tiny shares onto their payment databases constantly, but p2pool doesn't operate that way.

Does P2pool support multiple pools? Can run litecoin and bitcoin on the same server do or I need to run two separate P2Pool servers?

You can run them on the same hardware, but you have to run them seperately.  ie. 2 processes each in it's own window from 2 different folders.  Also , make sure you don't have any port conflicts.

So basically they can't run from the same server, I would have to create a P2Pool2 folder and install P2Pool into it to run Litecoin say, and P2Pool3 to run Doge coin, etc.?

I was thinking about creating a public P2pool node. What kind of hardware and bandwidth would I need? Lets assume I get 1 TH.
I presume you mean you have 1TH?
1TH is probably somewhere close to the hash rate you need to reduce the extremely high variance that p2pool creates.
(as I pointed out before, 150GH/s had ridiculously high variance)

Merged mining allows you to compare mining results with multiple parallel blockchains that are compatible, so essentially mining two coins for each set of work.

You can only merge mine with additional compatible coins made for merged mining like Namecoin with Bitcoin.  You can't merge mine Litecoin with Bitcoin.

Not exactly - you can run fwo instances of p2pool Bitcoin+merged mining and p2pool Litecoin from same folder, I am running them like this, no problems.

So if i do merge mining with P2Pool how do the stats show up on the front-end for the other coins?

They don't. You are blindly solo mining.

^^^ what bitpop said...

so when you're merge mining, Bitcoin will be pool mined and any merged coins will be solo mined.  You'll see the occasional "Got new merged mining work!" in the commandline display and any found block rewards will show up in the various coin's wallets.

Be aware it's solo and people using your pool will help you get alt coins, they can't get any. I like it as a free fee

Otherwise I guess the coins have to be setup on different servers, same hardware, different ports?

You would use a merged proxy in that case

Without it it will mine to an address from bitcoind. Usually you want to mine into another wallet

thank you, i ve asked the wrong question :-) i meant the --p2pool-node feature or -n.
you connect to another node i think, but for wich purpose?

That's so you can specify a peer connection to another node you trust.  Typically if you know certain public nodes are always up-to-date and run continuously, you can directly connect to them on top of the random connections.  Some people also use them when they're setting up multiple of their own nodes across CDN or Colocation providers to make sure they're nodes are always connected to each other.
