Would be quite the clusterf**ck tough. Also I fear a lot of lag, and a certain diminution of the part of the non-BB and non-CV in rooms. They'd need to increase default room size to at least 84, if not 90.
I predict lots of server instability if too many of those rooms are host. At any rate lots of crash. More than now I mean, since there IS lots of crashes already.
Current numbers are quite nice as far as I'm concerned, maybe a few more BB could be nice, but not double the current ammount thats for sure.
