Last Day To Sign up = 5.22.2009
2009 May 19
That’s right. Mobicamp registration is open until 5.22.2009. Hop on it folks. This Friday is the last day to sign up (it’s already packed!) for Mobicamp. 
EDIT: T-Shirts are first-come, first-served for attendees.
I’ve been developing an idea using RFID technology.
