About satgate... many ISP's use it... but ask them, what is size of dish and cost of equipment. I dont think on this forum someone can buy DVB-S2 router (around $4000+) and 5 meter dish (to use for 8APSK modulation). Ahh... i forgot. Noone will sell you less than 512Kbit/s CIR on this carrier, which is not less than $500/month.
About other - public tariffs, it is for end-users, yes. But capacity cost on satellite is comparable with prices of internet in lebanon. If you want throw your money in air - sure you can do it. At least i must warn about it.

www.d-v.ru (sorry russian, but they have interesting tariffs)
www.spacegate.com.ua (also possible russian)
Sorry, have to go. Just type "satellite internet" in google...
But as i told, current prices for satellite capacity same as cost for capacity in lebanon.
