[AG-TECH] AccessGrid on PDA devices

[R. P. Channing ["Rick"] Rodgers]

Fabrizio,

Motorola Labs (http://internet2.motlabs.com/ipaq/index.htm)
and our group at NLM (http://etg/project/index.html, see ASKLEPiOS)
have both experimented with using vic and rat on handhelds, but using
the familiar Linux kernel (http://www.handhelds.org), not PocketPC
To the best of our knowledge, no one has yet developed an AG
client for this platform, though it is very much on our minds (but, as
Derek rightly remarks, poses daunting GUI design challenges).

I don't know about Motorola, but in our work several years back, the audio
latency with using rat via 802.11 wireless was crippling.  We are hoping our
latest efforts on new iron will improve that.  We have a huge to-do list
of project ideas related to this work -- if you are capable, serious, willing
to stick to open source based solution, and have time on your hands,
get in touch.  :)

Cheers, Rick Rodgers
