Promising news on github:

Just to update this thread, it seems that this discussion is mostly stale now. We (at MtGox) will implement this new hash index in our transactions database and start working with it (we will announce a maintenance as we will have to stop bitcoin deposits too during the database schema update) and will start providing this new hash when customers are withdrawing bitcoins, litecoins, or any other coin based on Bitcoin we may support in the future.
We will also provide an API that will allow our customers to use this hash to retrieve the transaction hash as seen in the blockchain once the transaction is confirmed, and will hope others (blockchain.info?) will index this value one day.
We also invite other exchanges and businesses which may need to keep track of bitcoins they send to use this same method, since dealing with multiple variations of the same thing wouldn't be very productive.
If nobody does it, we will also post some test vectors for regular (in=>out) transactions in the near future.
Indeed Mark seems to be pretty active nowadays on GitHub/IRC, this is probably the "quick fix" MtGox was talking about in 10th Feb. announcement.
It's a (probable) step forward and I guess they'll have to enable the btc withdrawal one day anyway, the sooner the better for their longrun even if Mtgox is currently buying all cheap coins to sell it premium while everyone will need them to run away from mtgox.
If Gox goes down, there is no way they will pay fiat holders v.s paying btc holders, if there are really insolvency holes there, the btc hole will be the one that is easy to fill up, so forget about selling your btc and hope you could somehow withdraw fiat as your "exit strategy"; you will be trapped there forever and once btc withdrawal resume, you will be paying huge premium to buy btc at Gox to exit, hence being Goxed twice.
Totaly agree, I can't understand why everyone is selling btc half the price they paid them some weeks ago.
