I think you can do this fairly easily, mostly using nginx conf and
eventually 3rd party modules.

You could use headers_more[1] to always return the Alternate Protocol
headers.

Or this Lua snippet [2] (see ngx_lua module [3]), which will only
adverstise SPDY if a client is not already using it.

Happy hacking,
Matthieu.
