I wonder what you are suggesting cell phones should be able to do here?

Text messages to other phones in direct range, ideally voice calling as well, using only built in software.

Also (more) seamless direct data transfers. Eg. sending a photo to a friend standing next to me without it going through some Cloud on the Internet.

With which radio?
