[grc] How much bandwidth to run a VPN?

[shhhhh]

Howdy collective expert mind! 

How much bandwidth do we need to run a VPN as our STL? We are also
building a microwave STL but it's taking longer than we planned-- of
course! And yes, both ends will be on the same network. 

Related to this, the (very) local ISP is offering us public or private
static IPs-- which is better/worse? 

We're trying to get on-air *this* week-- yikes!
