I think we need osu! to be available on Steam, with supporter access to be bought with the DRM (Steam Wallet/direct payment)
In my opinion, having osu! available on Steam will increase supporter tag purchases and number of players in overall.
This is possible because of the new Steam Greenlight. http://steamcommunity.com/greenlight
I found old suggestions to add osu! to the Steam platform but it wasn't possible like it is now, since Steam didn't have Greenlight at this time.
Also, this should spare some bandwidth of new players downloading the game since it'll be downloaded through Steam's servers.
