Tickets for Google I/O 2011 sold out in less than an hour, a sure sign that there’s plenty of interest in Google’s developer ecosystem, and so the search giant has decided to throw open the virtual doors to the conference. Google I/O Live is, as the name suggests, live streaming from the Moscone Center where the event is being held, free of charge to access.

There’ll be cameras in the two largest session rooms covering the full 9am PST to 6pm PST keynotes on both full days of Google I/O, covering not only keynotes but Android and Chrome developer sessions too. Google is also aiming to get HD video available of any session not streamed up in under 24hrs.

All the feeds will be captioned (including machine-translated foreign language support) and virtual participants will be able to ask questions and those with the most votes will get answered. Google I/O kicks off on May 10 2011, and Android Community will be there to bring back all the juicy details from the opening keynote.
