I'd have the system automagically send back an email saying "I'm sorry, the transaction was aborted at your request" every time the user drops the connection... in the hope that eventually they'd learn :-)

Perhaps log a "starting transaction" and "transaction complete" at either end of the process, and then periodically scan the log for started-but-not-completed...?

Update: changed subject back to something relevent.
