Sweetpea Manor Musings

I've a friend who has a relative that is being called up to go to Afghanistan for a year. She wants to use Skype to stay in touch but doesn't know what she needs to get for that to happen. Does anyone here know what sort of hardware is best? I imagine a laptop with a webcam and wifi? Is there a internet provider that the military have to use over there? Any help is deeply appreciated.

Thank you!
