I helped a chap run base camp back home so his teams families could watch their progress a few years back they did the Mongol rally in a 1.3 Hyundai Accent.
They got all the way to Ulaanbaatar without even a puncture iirc!
Trying to explain to a none geek how to update when in the back of beyond was helped by SMSing to Twitter where the teams position could be tracked was difficult at times
