I'm aiming in the same direction you are -- a single chunk of code
that will say "you're logged in" or "you're not logged in" for the
entire site. However, it would be application agnostic (e.g., you
could log into Mediawiki or WordPress, but logging into would would
automatically log you into the other), so it's not sharing any
applicatin-specific cookies.

That said, you could very likely get WordPress running off the
MediaWiki cookie if it contains the username; just check the
MediaWiki cookie and call wp_set_current_user() from a plugin. I don't
know about getting MediaWiki to run off the WordPress cookie, because
you'd be changing MediaWiki code at that point (you shouldn't have to
change WordPress at all). The usernames would still need to exist in a
synced or shared table in both cases, but I assume you have this taken
care of.
