No, but there should be. Someone should talk to Jeek about spawning his bot into a #TMD_PlayMWS room or something. I'd head it up, but I'm only on IRC a few hours here and there.
I also suggested doing so, but I doubt there would be very many people connected at once. 
As for ArthurKing's questions:
I myself really like Magic Workstation. It's never difficult to get a game going for any format. Type 2, and Extended players are on it most, but there are usually a few Vintage players (some of which use TMD) on there (in MWSplay) at almost all times. Your opponents can be from all over the world, which can be either good, or bad. Unfortunately for some, not everyone in our world speaks the same language, so you may find yourself playing someone who is trying to talk to you in French, but you are sitting behind your monitor having little idea of what is really going on. Although, foreign players can still be good players, and great people to talk to, but if you still choose to avoid such occurances, you can use the software at certain times a day. (E.G. not at 1AM)
Overall, I like MWS over Apprentice, and has proven to be a fun way to play the game.
