Probably more like an ISP problem. See http://www.gnutellaforums.com/showth...ight=satellite
In fact, if use the search button above & type in satellite, you'll get a lot of results.

Satellite per se is not necessarily the problem. The question is whether p2p use is being controlled due to the high bandwidth it uses. However, some satellite set ups may have their own hardware firewalls. I think I remember someone saying they could downld but not upload on their particular set up.
