I found this older article from TheFeature.com about Wireless Health Care and Diabetes called One Guy, an Insulin Pump, and 8 PDAs.  I this after a trip my wife and I went on across the U.S. where I had to manage my diabetes through multiple time zones.  Also, I had just begun using an Insulin Pump at the time.  An interesting read, IMHO.  It also talks about wireless healthcare and my PalmPilot application, GlucoPilot.
