Have you started thinking about VoIP applications? I can't see myself
using a laptop on a parkbench that often; more appealing is the idea
of widespread outdoor WiFi coverage with a dual-mode GSM/WiFi handset
to reduce the number of minutes I'd use on a cell phone plan. I think
most such handsets use SIP so getting VoIP to work with only WWW, ICMP
and DNS would seem circuitous.
