What Erik said. All the satellite Internet providers use geosynchronous satellites, and that means pushes the round-trip time through the roof. It's death for any kind of interactive protocol -- RDP, SSH, even AJAXy web sites. There's no way around this -- it's a speed-of-light limitation. 186,000 miles/second -- it's not just a good idea, it's the law. Sat is okay for streaming -- like a TV station, or a file download. Latency doesn't hurt because you're just pouring bytes into the pipe. Even a two-way voice channel is workable. There ends up being a noticeable lag between one person stopping talking and the other party starting, but it's bearable. But Even web browsing would be too painful if it wasn't for the special "acceleration" the sat companies do. They do things like spoof the TCP handshake at the client end, so they can get the actual "GET" request into the pipe without having to wait for the SYN-ACK to come back, and use funky proxy servers to package multiple web page resources into a single stream. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
