Nice to see you here! If you are doing the events at FAM (both education, fundraising, and exhibits), then FresnoArts.net is a must promotion tool for you.
Enjoy and see you soon at FAM.
PS. You know what I thought of as a configuration for your network, try getting a wireless router with switch, then plug it directly to the modem. You might need to get the DSN configurations from the ISP (or not). Then connect the workstations directly via wireless --- this would take away latency I hope. As I mentioned before, I tried the switch and it got frustrating so good luck!
