If not, simply add a value that contains random data that can be set to "expire" after so much time (15 minutes). Probably stored in a DB until they submit the data. Also remove the value from the DB after it's been submitted to prevent additional submissions. To aide with slow typers, make sure the form redisplays what was typed on the error page... might want to suggest they copy/paste it to a new form, or simply give them a new variable on error. Either way, they need to resubmit... Just a random thought on 4 hours of sleep. Enjoy!
