I'm working on one (Score 1)

for my senior thesis. kinda. It's like AvantGO where you subscribe to channels but the channels are all administered by hand through a web interface. The Palm client connects to a custom server using TCP/IP so it can take advantage of a bunch of connection types. hopefully. Anyway, despam and email me if you want the code or some chapters from my thesis. It's all C/PHP/MySQL and I'm not really sure if I have to do something special to GPL it with the MySQL in it.
