Hi there,
I've developed a system over the last few years and believe that it can be of use. It runs natively on J2me, Android, Blackberry, iPhone, CDC, Palm and Windows CE devices. Essentially this means only one codebase needs to be supported to target all of these platforms. It utilizes XML ( HTML superset ) to render interfaces on the fly and screenshots are on my Profile / Can be sent as proof of concept. Functionalities include compression, AES encryption, Location, Bluetooth and Ajax capabilities to name a few. If interested, then please feel free to contact me. I look forward to discussing your project at length.
Regards
JB
