Last week I was watching live video feed from Warren Crammer from Wurtsburo flying in thier ASK21. I could hear him talking to me and I was texting him (while someone else was flying of coarse).

Not sure why you think live feed video is far away?

Sure, if there are good mobile phone networks in the place you're flying. Much glider racing around the world takes place in areas with nil or weak mobile coverage.
