I took a look at the ventrilo thing and I did not see where it actually used a database that could be integrated with the threads user database table. Unless I missed something? the Main reason that I wanted the integration was so I would not need to become involved in setting up accounts for people to use the server which is a private server with multiple rooms.
I also use webpost which you can view at
