Well, none of the schemes proposed so far actually deal with the case of subtle vandalism. They're all assuming it's possible to determine whether an edit is good or not. The only fool proof way of doing that is to send someone to check it out in reality, which is going to be a fairly intractable problem. The obvious vandalism is the low hanging fruit, and the obvious place to start if you're aiming for a more stable map. I'd imagine people will do this for smaller areas in a similar fashion to how we handle the coastlines for the cyclemap (ie: we grab the data every so often, and just keep the old data if the new looks too broken in a critical place -- at that point I usually try and fix it of course).
