As you know, I'll be teaching 3 tutorials at LISA this year (Intro To Time Management, Advanced Time Managemente, and Ganeti/Build a private cloud). If you can't attend in person you can still watch over the internet. The cost is about the same as being there, and there will be a chatroom so that you can ask questions just like in-person attendees. However, you save money of travel and hotel.
See you there at the conference or via the interwebz!
