TechCrunch featured - Marauder's Map for Networking at Events

Looking for: Designer, Developer
What if you can search for people with specific skills, or from specific companies/industires, and see them displayed in a real-time map when you are networking at an event? Just like Harry Potter's Marauder's Map. Wouldn't it be fun to then play a game of tag so that your "target" knows that you are "hunting them down" and he/she has a choice to cloak/uncloak?
