We don't use video because I feel its a waste of bandwidth, and plus several of us don't have cameras, so the clothing policy isn't a issue for me, but I would see how it could be.
We roll VTT dice only.
My very first online session, I was a player, and one of the group proceeded to eat his dinner not just with a live mike, but making yummy noises and explaining how good it was, while we were in the middle of a fight. Then got deeply offended when I advised the GM I missed what he said because of the noise of mastication. Needless to say, that was my only session with the group. If I hadn't been there to get a look at online gaming, I wouldn't have stayed for the whole session.
The 'wandering token' issue has been a problem for me in the past, but I solved it by having restricting movement out of combat; the party leader gives out a distance, usually around 20', and everyone moves, then they stop and evaluate. Its become popular, because now they aren't running into ambushes while badly spread out.
A lot of my table rules from the F2F days have not carried over, but online gaming brings new rules into use.
