Short,
There's a 6000 on SP over 6ft dish running 130kbps upload/1000kbps down. I ran some Skype calls over it about a year ago, it actually ran better then my system here at the time. I've since upgraded my system here to a 7700 with 512/2000kbps service. And we have an iDirect system that works even better for VoIP, Skype and Net2Phone.

If they tell you it won't work over satellite, they didn't try hard enough!
