Ok, I've just tried with Firefox 11. You have to go in "about:config" and set
"network.http.spdy.enabled" to true. Then the code snippet works (it prints
"spdy/2").
My OpenSSL version is 'OpenSSL 1.0.1-beta3 23 Feb 2012'.

I don't have Chrome to test, but perhaps there's a similar configuration option.

PROTOCOL_TLSv1 works here (with Firefox 11.0).
