We'll likely be doing BSDCan 2009, if our tutorial is accepted (should be, as we've been accepted for the past 3 years).
EuroBSDCon 2009 is a possibility also. Due to cost, less likely, but we hope to be able to make it.
We had hoped to make it to NYCBSDCon 2008, but that didn't work out. We'll almost certainly make NYCBSDCon 2009, but the chances of a longer tutorial session there are slim (they don't have long sessions like BSDCan and EuroBSDCon).
We may do an online session sometime in 2009, similar to what we'll be doing at the Cons and did this past year at BSDCan. That remains to be determined.
