Maybe instead of 5 seconds it aught to be "before the transaction is fully confirmed." @p{par} The only drawback I see is buggy clients that might have bugs that cause 'honest' double-spending mistakes. @p{par} Oh, and merchants would have to explain to customers whey they kept their double-spent coins (although the merchants could easily produce both transaction IDs to show the world that it WAS a double-spend, so they shouldn't have to worry about their reputation being sullied).
