Hadn't thought of that one. Sounds plausible.

There's also the fact that many apps you run over VPN are designed for a
LAN environment with very low latency. So they use many short data
exchanges in a row -- quick on a LAN, but deadly slow on a satellite link
with its 700+ ms latency. You can try that with Windows Explorer: barely
workable over a VPN link between standard broadband locations in the US,
almost not workable over a VPN link between standard broadband locations in
the US and Brazil, and not workable if there's a satellite link it between.
