In London UK only.
Exchange in person for BTC

In London UK only in exchange for about 2 bitcoin.

But then I came across this https://blockchain.info/tx/d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599

I see two reward blocks, so the same transaction id exists in two different blocks.
The output is to the same address and that address has only 1 input so it clearly is the same transaction but it was included in two blocks.

Why is that?

Is anyone working on a payment processor for alt coins(like bitpay)?

What would be the challenges in implementing such a system?
I assume choosing the "right" coins will be an important decision to make in this case.

Would love to get some comments and ideas about that. 

As mtgox is the biggest exchange out there (and I hope this will be changing with resent events)
This sharp spikes are very bad for businesses trying to make it in the bitcoin market, for example bitpay accepted transactions before the drop in and has probably lost over 50% in conversion value in these 3 hours.

Perhaps mtgox should consider

1. stopping all trades if market value goes above or under a certain percent(5% 10%) this will stop crashes and prevent unwanted bubbles which are so harmful to the bitcoin economy, especially now in its vulnerable early stages.

2. have a limit for a person in trading frequency and volume this will prevent panic sell (or buy)

3. Its not uncommon for exchanges to stop trading when markets go wiled to any direction, and if mtgox had issues with there servers (as per last press release) they should have stopped trade for some hours.

just another financial dude bashing bitcoin.
One thing he got right is the deflationary problem.

BTC  is the awesome bitcoin.

What I am not sure is what are all the other coins?
LTC, NMC, PPC, TRC etc..

If coins they are then whats the point if we have BTC?
Tried to find some documentation around with not much luck.
