I think it would be fun. Vent is a great program but to host a large number of people you have to buy licences which gets expensive very fast. I run a teamspeak server off my server for free and can host 100 members at a time. The quality isn't as good as vent but it gets the job done. You can find Teamspeak at
http://www.goteamspeak.com also if you need someone to host it I can take care of it for you. I'd like to be able to help out the community some more, so let me know if there is anything I can do.
