If you see this technology and think "wow! that solves [problem I already have]" - then it's great.

Otherwise, you buy a couple, set them up, spend a week or two sending very slow and unreliably forwarded messages that mostly amount to "hi! i have an ACME 32ABC radio! What do you have?", and then put it in a drawer or sell it on.

Just like ham radio, really.
