We have Opera Mini that uses several different protocols, both similar to  
HTTP as well as of the persistent TCP connection type. These are all  
binary protocols using different versions of request-response, RPC, push  
features, as well as compression of different sorts. We have Opera Turbo,  
which is essentially a modified HTTP with prioritized, out-of-order  
pipelining and some simple compression. Finally we have integrations with  
different 3rd party technologies, some of which are mentioned on the press  
release pages

Not really an answer to your question though, I'm afraid. I would need  
more time (and meetings) to collect that...

I'm using the same data as the  
http://www.eecis.udel.edu/~amer/PEL/poc/pdf/SPDY-Fan.pdf and when using  
the evaluation set they use I actually get somewhat better compression  
values (probably due to better header normalization).
