GPS Data Logger Software - BT747

Hi all,

I have a 747A+ GPS Trip recorder that I use to Geotag my photos. On some of my longer trips (weeks) the trip recorder fills up the number of data points and will stop logging. What I normally do is take a laptop with me and download and clear out the device every couple of days, but obviously this involves lugging a laptop with me which is not always convenient.

The different iPhones do not have an official Java Virtual Machine (yet), but alternative solutions seem to become quite viable.

The most promising solution for BT747 is 'xmlvm' - a toolchain that translates Java (and some other languages) to an intermediate language 'xmlvm' - an xml description of the program. That description can then be translated to 'Objective C' - the language used for iPhone programming. Important parts of the iPhone library have been given a Java alternative which means the program with the iPhone look on a standard Java Virtual Machine (J2SE).

I've started setting up a project for that (http://www.bt747.org/node/164). More background is in the forums (http://www.bt747.org/node/112).
However, a volunteer is needed to do the real development. So if you feel like it, let me know.

Don't know if this request belongs here, but with the new iPhone 3.0 it seems like it might be possible to access bluetooth GPS loggers. If so, I would love to have an iPhone app to download tracks to and also be able to access realtime GPS data from my iTrek Z1 logger. I have a first gen iPhone without GPS, but also I know that using even the iPhone 3G as a GPS data logger is not ideal, because:
- can't run logging in the background
- hurts battery life
