Good luck finding an example of actually using it to serve pages though. My Google-fu isn't normally that weak, but I couldn't find anything helpful. :[
I usually get lucky with using "golang" but the best I came up with were other people asking how to use the SPDY server along with ListenAndServe without any helpful replies.
You're not the only one. I can't find a single person who tried the Apache SPDY module. There is also no recent activity on their discussion board, which is not promising.
The real problem is lack of good server implementations now. Google has whatever they use, but basically nobody else does.
Community of the web, let's get this rolling!
