If you're getting deep enough into the Mailman code and wiki code to 
patch their existing login systems with OpenID, you should be able to 
rig something much simpler with, say, just a cookie. This might lead 
to security problems if you're hosting each service on a different 
subdomain (with cookies delivered to *.domain.com) AND users get 
their own webspace on subdomains (since then users could read session 
cookies from other users), but if all the subdomains are official you 
should be fine :)
