@Chip Bennett - Good idea, and this is where getting surveys and feedback from your area and local meetups would help you determine how successful that might be. Or maybe just do a HALF BuddyPress (morning) HALF bbPress track (afternoon).

The only problem that I could see is that adding tracks means possibility of missing opportunities to introduce people to the these plugins (given the choice people might choose another track because that's what they know they want to hear). That's why we did one-track day devoted to BuddyPress (we got marketers, project managers, etc - when asked the audience who never seen/heard of BuddyPress, half the hands went up).

That aside, I think the concept holds merit and i would love to see someone give it a try.
