When Google opened registration for I/O, demand from the public made the Tickle-Me-Elmo rush look like a small group of seniors enjoying a day at the mall. After the servers were slammed for a total of 59 minutes, every last ticket had been sold, at least according to Google. At the end of February, tickets for the event (and the supposed hardware goodies that come with attending) were being hocked on eBay for $2000. Given those two facts, I'm guessing you didn't manage to get your golden ticket.
Well, if you are a talented developer, there is still one last ray of hope.
