I'll be presenting on Free Open Ghost (FOG) at PICC '12 on Saturday May 12th with Todd Macdonald. I'll be talking about the technical side of implementing FOG and Todd is talking about training users to take the role of level 1 technicians using FOG.
There should be some other interesting talks there as well.
