The allegation that an address that MtGox's controls still holds all the Bitcoins but that they've lost the key is fascinating.

If true, how can MtGox prove it lost the key? If he walks away, he can wait 10 years and then transfer the funds out and spend them.

But if false, can we demand he produce the key?

What if someone else entirely different has the key?

It's all fascinating.
