I'm not sure I understand the question here, ie whether it's asking whether you can pay for service (certainly, via Hughesnet or other similar service), or whether you can monitor what other people are doing on the internet (sometimes). Re the latter, it seems like a year or two ago, this was pretty straightforward, although I may be wrong. Ie I'm pretty sure that when all those feeds up there were "DirectWay", that they were just plain DVB/IP, and you could monitor the content, however now that they are "HughesNet" or whatever it's called, it seems like you can't easily monitor the content anymore. There are still other services up there that CAN be monitored though.
If you have a
Twinhan card, it comes with a program called VisionData, and if you run this, and give it the freq/sr of an internet feed that is in IP/
DVB format, it basically turns the Twinhan card into a network card. Same thing with the Broadlogic card. There are a few other ways of turning your Twinhan into a network card.
Once that card is going, you can run a network sniffer, like Ethereal or many other such programs, and you can watch data flying back and forth over satellite. I had always thought it would be neat to do this, and ping one of the IP#s being monitored over my regular internet service, just to see if my PING showed up on satellite.
I've run into several transponders that seem to be regular internet using IP/DVB, based on the very large number of IP#s transmitting data over the feed, however the main HughesNet things seem to be using some NON-DVB format. Ie they don't even give a PID that you can monitor. You can lock on the signal, but it doesn't even show up as a transport stream with PIDS, so I guess you'd need the Hughesnet hardware to monitor them.
