Really looking forward to this!
I wouldn't expect IBMA to get any less conservative than they've always been. They are great an embracing the artists that keep the tradition of bluegrass alive, as they should, but they also should be embracing the bands that are taking the music in new directions. The Avetts and CCL, as you say, are great examples. Unfortunately, the IBMA members have always been very cold to these folks, even when the organization have done their best to help them out.
Change in bluegrass has come at a glacial pace. Look no further than the IBMA awards that have been handed out for more than a decade and you'll see the same names pop up on the list time and time again. Dixieland music is great, too, but strictly defined music that doesn't allow change can end up being a museum piece. A great museum piece, but a museum piece all the same.
It would be nice to think that this move to Raleigh will change things, but past experience shows that this isn't going to happen.

A quick fact check on this post of local representation at Casbah: In 2012 so far, 78% of the bands that have played at Casbah were local, from the Triangle, and 22% were from out of town. Seventy-eight percent comes out to 253 local bands that have played at Casbah in 2012.
