As far as I can tell, there isn't sufficient interest in running a Beta2 server. There have been few comments on the new release and no bug reports at all. So, if you'd like for there to be Dedicated Servers for Beta2, I suggest showing some interest as well as having your friends play the mod and give us feedback. When enough interest is being shown, an official dedicated server will be run and a new patch will be issued.
