[PD] Open alternative to RJDJ?

I'm gathering information currently for a potential exhibition involving mobile sound devices for 2010. My criteria are as follows:

1. Gathering and processing of environmental sounds
2. Open source software and open and/or accessible hardware
3. Doesn't make only techno music! ;-)

and optional:

4. User's location and/or movement become processing criteria
5. Ability to network with other devices to share sounds and information

The RJDJ project sounds like it fits the first and fourth, I don't know about the others. I agree with several of the posters on this list who were suspicious of a project using free software but geared only towards expensive hardware like iPhones. But I don't want to totally discredit the momentum that's gone into this project. So my questions are:

1. Can RJDJ "scenes" run on other platforms (Palm, iPaq, Gumstix, Linux

iPod, whatever?) 2) Is anyone working on an RJDJ-like/compatible platform which is actually open and accessible?

I will drop by the Berlin RJDJ sprint with these kind of questions in mind in case anyone wants to discuss them in person.

best! Derek
