Kevin Shockey announces:

For the first time, the O'Reilly Open Source Convention will feature a Microsoft Windows track. The focus of this track will hopefully capture the growing momentum behind projects like Mono, mojoPortal, iFolder, TomBoy, F-Spot, Banshee, NHibernate, NAnt, and Nunit (just to name a few).
