On this subject, as part of the IPv6 testing I've run a JS tester on ENWP for a couple of months now which has determined that for hosts able to run the JS tester, protocol relative urls (i.e. <img src="//upload.wikimedia.org/foo.jpg"/>) work for all clients.
If protocol relatives turn out to be universally supported they would remove one problem from doing a native SSL deployment.
I can't comment on compatibility with clients that do not support javascript / don't execute the v6 test for some other reason.
So, could we/you just add a couple of small images to some unobtrusive place in the MonoBook skin on enwiki, with one using a protocol-relative URL and the other not, and see what happens?
