AGGGGGGGGGGGGGGGGGGGGGGGH!

Satellite VPN!  Latency is your enemy.  Because packets have to travel
96,000 miles, there is a 500-600ms latency.  TCP/IP was designed before
satellites, and it uses this latency to determine line speed, and the
long latency can kill you.  In the early days of satellite, TCP/IP was
absolutely awful, and still is with some vendors.

However, nowadays, most satellite vendors have TCP/IP accelerators which
spoof the packets in order to avoid the latency issue.  Rather than wait
for a response from the other end of the satellite, the satellite vendor
spoofs an acknowledgement back to the sender (and later suppresses the
real acknowledgement).

However, with VPN the packets are encrypted, and cannot be spoofed.  The
packet has to go all the way to the receiver and back, and thus, VPN
over satellite is still plagued with latency issues.
