We were also discussing this at LinuxCon, and OAuth or similar paves the 
way to some other nice things, like easier single sign on/integrated 
systems, and an easier way to handle using the archives like a web forum 
to allow participation by those who prefer that mode of communication.

There was definitely interest in having a setup where people could 
mass-manage subscriptions to lists even when they're on different 
servers, which I hadn't thought of but can see the advantages for users...
