Ok so probably not my best idea. But I was talking to someone here in DC and had the idea of doing facetime tours with the iPad or iPhone of historical tours in Rome and other places. So older people stuck somewhere could have a live tour as if they were there. Kinda nerdy and you have a time zone issue in some cases but might be cool.

And of course you could just record it and send it to them. Maybe a personal tour then, you send college kids abroad, and then get a list of places someone wants to see and they record walking to those places, the bus trip, everything and then record the places.
