I understand the motivation to going to a binary protocol for a SPDY inspired HTTP 2.0 but I would have liked to see an ascii based protocol similar to what jgrahamc proposed last year [0]. I thought it was a much cleaner protocol to read and understand, and much more in tune with what the web is supposed to be. Why not keep the clever binary stuff separate in SPDY, endorse it though the IETF and keep HTTP ascii?
