I was going to mention this but failed to do so.
At the very least, do some testing first to make sure that the latency =
isn't going to introduce unforeseen issues. Case in point, the Chicago =
satellite-based network that I manage is sometimes used for Police / =
Fire / EMS dispatching. The City's Computer Aided Dispatch system ended =
up crashing during an early test when it was discovered that it couldn't =
handle the high latencies encountered on satellite links. This required =
the vendor to adjust the code to deal with these issues. Granted this =
is an extreme example, but the point is that the physics of satellite =
links can do all sorts of things to applications that one might not =
expect.
Cheers,
Ryan Wilkins
