Hi!
Sorry, I've not been doing Xen coding over the Christmas / New Year period,
partly due to being away and partly due to being ill.
I'm back in Cambridge and getting back into things now. I'll be trying to get
a copy of the code online later today and will point you at it when it's
there. Currently it doesn't actually *do* very much ;-) but it's a start on
what I think could turn into some interesting stuff!
Cheers,
Mark

Dave: Just a question. What use is a unicyle with no seat? And no pedals!
Mark: To answer a question with a question: What use is a skateboard?
Dave: Skateboards have wheels.
Mark: My wheel has a wheel!
