Bart De Smet's on-line blog (0x2B | ~0x2B, that's the question)
I'm playing around with Monad for quite some time already (see http://community.bartdesmet.net/blogs/bart/archive/2004/10/19/445.aspx). Apparently I've forgotten to post about some experiments in Monad (or I can't find it back :-s). However, you can play with it yourself right now. Visit beta.microsoft.com and use the mshPDC guest ID to login. The beta can run on Windows XP and Windows Server 2003.
Have fun (and time? :-o).
