Perrin, a penny just dropped, are you aka Perrin Harkins? If so I hope you found it funny rather than insulting that I refer you to the mod perl list. :)
Yes, that would be me. I'm not actually implementing ticketmaster.com, just talking about what my friends there built. They have a queuing system which provides status information so you can tell your place in line.
P.S. Send me your Unreal nickname and I'll look for you next time I play.
