Speaking of GPS, today I did my first real mobile test of my live GPS
"DougTracker" data feed. I was sitting in my car in cupertino, with my 
wearable computer connected to the net via 2.4Ghz wireless radio modem
(metricom). The system was able to send a position fix every 3 seconds
to my home server 20 miles away, updating a web page that tracks my 
location. Not too shabby for a measly 28.8kb connection. And I am 
amazed at the ease of software development using java remote method
invocation APIs. Truly a peice of cake. The really cool thing is that 
metricom is upgrading their network to 128kb this summer. That means 
dual channel ISDN speed, no wires, anywhere in the SF bay area!

Wow. I am speechless. That is truly amazing.
