There are times often I go to a multilayer match and the host puts up a beatmap that was never uploaded onto the osu! servers. I think the ability to share beatmaps similar to ftp just with *.osz files within the chat would be nice. The game reads the map in the songs folder, sends it over the internet to the other player, and adds it. A simple command like "\share" would work. This would also enable modders handing out beatmaps to test to other players before they upload it. I think people will settle on this to be a supporter only feature. Well, what do you guys think?
