Do you allow the sender to re-spend it?
If not, then you didn't solve anything; the coin could still be sent to a wrong address and lost forever.
If you do allow resepnding, then the recipient can no longer trust the transaction; every transaction will open a potential race between the sender reusing the coin, and a recipient unlocking the password.
So, password protected transactions are no-go for Bitcoin.
the status is untill the transaction is not confirmed or canceled you can't send bitcoins.
its cant be lost because if he doesn't confirm in 1-3 minutes or how much time u want.. it is canceled.
