There are several companies providing Internet access through a
satellite link. Easynet used to do it, Starspeeder do now.
It's good for download intensive applications but the latency is poor
due to the way your uplink traffic has to go through another ISP over a
slow link.

Are you sure about that? TCP/IP is a two way process. How does the
mailserver know you've received the mails if your not able to send any
form of acknowledgement?
