I've read that a double spend attack is really only possible within a very short period of time (literally a handful of seconds) once the transaction hits the network. My original point was that you can grant almost immediate access because it's 99.999999% certain the transaction is valid. Non tangible access to a website is one of the situations where it doesn't matter if one transaction in a million ends up being reversed after an hour.
