Sort of related - I know Brian recently mentioned hoping to put out a DVD in the near-ish future, like sometime this year-ish. Sounds like it's just a desire of his so maybe on whatever tour they may have planned for this year (he's spoken of "a couple tours"), they would have an opportunity to record. I could be wrong but I've never seen anyone who seemed to be officially videotaping any of the shows I've been to.
Regardless, I would LOVE a live DVD from these guys, and I'd hope for some behind the scenes footage as well.
