A change I've wished for for a while (but I suspect it is too big a change to
ever make it) is that a transaction announcement include the block the user
wants to base on. It would only be in the protocol message, not the
transaction stored in the blockchain.
The advantage is that (1) it protects against double spends without needing a
confirmation period; as a merchant I can instantly spend a 1-confirmation
transaction by creating my transaction with that 1-confirm as its "base". (2)
your expiry from memory pool becomes easy -- if the "base" is more than N
blocks below the current head, then that transaction won't be included.
Retransmission is possible with the base updated.
