Sat "terminals" are what you're looking for - a portable earth station, such as the Thrane 500, a small and capable device. You need to get a sense of her lattitude, as this will affect both the equipment selection and the service selection.
At this place:

25MB - $166.25 (that's about 20 digital photos from a 3 MP camera or a WHOLE LOT of plain text emails)
50MB - $325
100MB - $605
250MB- $11487.50
500 MB - $2875
1GB - $5,500.00. This is about the same as 1/2 hour of good quality video, a few hundred high-resolution photos, or 1/7th of the text of Wikipedia. (yes, that's five thousand five hundred dollars for a gigabyte of data use, makes you appreciate your DSL or cable modem, huh?)
You can hook pretty much anything to these terminals, they are, as far as the computer concerned, just another network connection or a modem. Battery life is dismal, you'll need a major solar array or other power generation system to recharge them.
Alternatively, you can rent a Satphone and use SMS, which is cheaper, but limited to 140 characters.
