Your initiation of a transfer and signing of the transaction are both your intent and consent, respectively.
No, as shown with the ATM example I gave you in the other thread. A software bug is not, and cannot ever be, consent.
1) these are not ATMs, certainly do not fall under the same rules and regulations (at present anyway)
2) I did not say the bug is consent, but the signature. What do you propose we do about this "bug" issue in the future then eh? Can I set someone up with a bitcoin wallet, send them all of my bitcoins with erroneously coded software and then prosecute them? I think not.
3) Do you know 100% for a fact that a software bug caused that issue? Provide solid evidence apart from an IRC log that it was not intersango's intent to send the btc and that a bug caused the issue
4) whether you want it to or not, bitcoin has no regard for "intent", you're thinking of paypal, those transactions can be reversed, perhaps PPUSD is a better currency for you
Ultimately you must be responsible with your bitcoin, because there is no forgiveness. If you code bad software that signs away your btc, that is your issue, not the receiver's
