Google mentions SCTP briefly here, along with some other alternatives: http://www.chromium.org/spdy/spdy-whitepaper http://www.chromium.org/spdy/spdy-whitepaper Their main reason for going with SPDY seems to be that rolling out an application-level protocol is easier, while rolling out a transport-level protocol would require changing routers and such. That is almost certainly true. Fixing the multiplexing problem in an HTTP-specific way rather than generally does seem like an unfortunate hack, but it's probably the pragmatic approach.
