This is a first-wave in that it's basically the North American part of the group will do the PFC program at MCAD before the two-day festival. (Sarah Glidden describes her participation here.) They'll be joined by a few European cartoonists, and then the show itself will have more guests, apparently.
That sounds like a fun thing to experience, and it certainly in on the tiny list of comics "things you get to do." I imagine 15 years from now there will be a ton of workshop opportunities related to festivals, but right now it's a pretty light group and the best seems to be this one. The invited-cartoonist list also provides the backbone for a solid show that we can all attend this August. I hope to be there.
