There are so many alternatives:
1) Get version 2.1.0 and client 2.1.4; you can host around 200 clients
2) Use virtual machines to run multiple instances on one server. Setup a virtual "client" on the server to connect to each vent-server that syncs audio across all vent-servers using audio routing, furthermore, you can ask your clients to download an addon program that attaches to the vent client which relays non audio info thru a syncing server program for managing all the individual server programs.
or 3) Download the crack (yes, there is one) or crack it yourself 8)
