That's fantastic work guys.

Please also keep in mind one of the end goals for integrating this  
into the larger 'health projects picture', namely teleconsultation  
with health professionals.

We need to create a souped-up version of a teleconference (video- 
chat) activity for the XO that allows for the parallel transmission  
(for example in other pop-up windows) of additional information/ 
communication: the display of this telemetry data from EKG's, the  
ability to pop-up text, graphics & images on the other screen,  
perhaps programming features that come from 'collaborative editing'  
type software, etc...

It is so wonderful to see all this stuff moving forwards, and it is  
my great privilege to get to work with you all on this. I really wish  
I could come to the Seattle Health Jam, but alas have no money for  

Take care all,
Josh Hehner
