Hi Jon

I think the 'restrictions' on VoIP and VPN are because they don't work on most (HughesNet, WildBlue, for instance) 
satellite platforms due to the very high latency.
There are a few,( http://www.skycasters.com/broadband-satellite-vpn/index.html ) who have designed around the latency 
problem, but they're not cheap either.<s>
