i was wondering, could this be used to develop the multplayer gameblender module?

I haven't looked much into twisted, but when I was developing my multiplayer framework a few months ago, I wrote my own server. The difficulties in writing blender multiplayer comes from the client side, not the server side. The way blender handles some things makes it difficult. I had many bugs and I got discouraged, but the server worked fine:)
