I with we had fhunter around to tech speak at us.
I do believe the above information is dated or regional.
Satellite Internet is not an available option in urban areas where other options exist, but I know two rural locales that use satellite and it is high speed ala cable. Dish type TV carriers offer it.
River et al are renting now and will purchase their own property is my understanding. Both are off the grid, and a dish can be moved.
The problem remaining is, off the grid electricity to power satellite internet.

I am on extended vacation from posting to EA.
There are different kinds of satellite internet. It is pricey, but, if there are no other alternatives, not outrageously so (about 500$ for equipment) +
from 20$ to 500$/month, depending on the traffic usage. This is on approximately DSL speeds (they claim 6/1 mbit downlink/uplink).
The numbers I googled from one of the russian companies.
This is for two way satellite internet.
There is also one way solution (uplink via cell phone/landline/anything, downlink via satellite), this one is cheaper, but can have higher latency.
In any case, with satellite it is not the speed that suffers, it is the latency.
http://rescomp.stanford.edu/~cheshire/r ... tency.html - this article, even as it is old, sums it up nicely.
Average round trip time (RTT) for ethernet connection for hosts in provider's network in my case is under 1 millisecond (about 14 ms to google). Mobile internet raises that time to about 100 - 300 ms (and in case of bad reception even higher, I've seen up to 3 seconds of round trip time and even more (it is not internet, it is suffering :-p)).
In case of satellite internet, you can not get lower than 250-270ms, that is RTT from geostationary orbit. Factor in the other latencies, and well.. it can go up to the same 500ms or more as the cell in bad reception (but at higher speed). There is also Iridium, they are low orbit, so have good latency, but low bandwidth (64kbit/s, like a phone line modem), and as far as I remember, not cheap.
Now for examples - latency above 50ms makes playing online games unpleasant, about 100ms... forget it, you will be dead meat.
Above 250ms-300ms, and your VOIP application will feel be really bad (multiple echoes + dropping out sound fragments, that sounds awful).
At about the same latency, you can not properly work with remote desktop apps (same effect, you start making bad mistakes in typing and all).
Above 500ms-1s and you can forget about any interactive applications. Forget about using webmail of the modern kind or any interactive sites actively using ajax.
The services requiring only bulk data would work.
Electricity is not much of a problem. If you have stable winds - wind turbine made from 200 liters drum + car alternator will give you enough power for you notebook
