yes, i understand zero-confirmations it's unsafe, the problem is the users, does everyone understand? they don't want to wait 10 minutes for a confirmation

of their online pizza purchase... they want it now.

I will support this and to keep the block-size the same if the bitcoin speed was increased to 2 minutes for example.
Then no problem waiting for confirmations.

Anyone know when 0.8.2 gets released?

It should never allow you to reemplace a transaction, or to change outputs,
it should allow you to give more priority to a transaction that it's stuck on the limbo of 0 fee/smaller fee transactions.

Only replace the transaction if it's the same transaction with bigger fee. to the same outputs.

Any other thing is not bitcoin, btc is not reversible.
or you just killed satoshi dice.

very exciting! every additional full implementation will make Bitcoin stronger and more independent in the long run.

I'm sorry, what is oracle system?

Yes, but if u get rid of transactions of these spent outputs, then u can't check proof-of-work coz it contains ALL data.
