Add to Richard for Ming -
Thee are limitations and growing commercial pushback from NT-based
receiver-routers. I would sugest looking at Linux-based solutions.

Subject: RE: QPSK modulator card / Vendors Needed
Gilat Satellite Networks, are both a service provider & a Manufacturer.
see www.gilat.com under the Skyblaster section, This is a modification of
the Skysurfer System, but using DVB technology as oposed to thier own
bespoke architecture.
The system is curently NT Based, I do not know if they ar planing a linux
version. However I think the Recive card is based upon the Broadlogic
Satellite Express Cards www.broadlogic.com which which do have Linux
Drivers.
The return path is a gilat proprietry system, which I belive requires a
costly hub based at the uplink.
I have sucessfully built a linux based router, using a Broadlogic DVB
Receive card for the High speed satellite receive. One ethernet board for
the local lan, and another used as a return path connected to a standard
satellite modulator via an ethernet bridge. The Hub site is built using a
router a DVB IP Encapsulator, and a bank of recievers with ethernet
bridges.
There are companies that are building comercial versions of the system
described above, but when I was last working on this project none of them
had implemented any satellite return path, hence the ethernet bridge setup.
