Yes, I have DirecWay (by DirecTV) because I live in the middle of nowhere and 'real' broadband isn't available. I just upgraded from the DW4000 to the DW6000, which is one modem instead of dual modems.
I've had it for over 3 years now (along with 12 phone lines) and it has been a nightmare. It rains, snows, humming bird flutters over it and it goes down. The download speed is decent, but the upload at best is 4kb/sec. Logging in to remote computers is SLOW. The latency is awful. Surfing web sites is slow... there's a really bad lag. I must say that the DW6000 is a lot faster than the DW4000 was, but it's a lot of money for crappy service. I paid $1200 for the hardware and it's $69.95 a month.
On top of the slowness and the latency, you are limited to 22 TCP connections in a 4 hour period for personal accounts and 30 for business plans which cost more. If you exceed the limit in 4 hours, your bandwidth gets capped down to nothing, to the point where you can't even load a web page and IM programs disconnect. On top of the TCP connection limit, you can only download up to 169MB in a 4 hour period, or again, your bandwidth gets capped because of the fair access policy they have. The government in the US has a lot of laws about satellite transmission, so that's one of the main factor's of it sucking.
I cannot wait to move to where I can get REAL broadband. There were days I was PRAYING for a dial up 21k connection. It's HORRID!!!! 
Oh and tech support? Ha! Have fun calling India.
