I think to expand the token economy, tipping should be added. It could allow you to give other players either set amounts (1, 25, 50, 100, 500) or a custom amount of tokens. It could also be integrated into custom rooms to send the creator(s) tokens for their hard work.

It could also create an environment where there is an actual ingame, interplayer economy, and a reason to have tokens other than to buy some more pizza and clothes.
