I'm also helping organize the first interop unconference, specifically on, yes, you guessed it, Cloud computing. It will be held at Interop Las Vegas, from 5:00-7:00PM on Tuesday, April 29, 2008.
The evening event has a candid and informal setting, with only a little structure—a dramatic departure from the traditional conference format, one in which attendees drive the content. A bunch of us will probably head out for some drinks and other random activities afterward.
Please feel free to get in touch.
