XenServer 5.5 is out

[Joseph Sinclair]

I'm hoping to be able to put one together in a couple months (perhaps September?).
I'm actually working through a bunch of virtualization stuff at work, and I'm thinking I can coalesce the stuff I'm learning about Open Source virtualization technologies (and lightweight Linux to run as a VM guest) into a decent presentation once I've finished.
