Won't this be too slow to be useful for anything except a proof of concept?

There's some overhead in each packet -- maybe a 4x increase in the number of bytes -- and bouncing between DNS servers will give you an increase in latency -- maybe an extra 500kbps -- but it won't be so bad as to make this unusable. I imagine IP-over-DNS-over-neighbour's-wireless would be much faster than IP-over-phone-line in most cases.
