There aren't any keyboard commands in the RF software, but once it's paired via bluetooth, you should be able to send/receive data with other programs. It would just need to be formatted the same. I'm not smart enough to do that, but it should work. I highly doubt RF has done much if any encryption on the comms between the 3sixty and tuning device (be it palm pc or laptop)
I hadnt thought about this idea before, I'd love to fix some eq settings on-the-fly for some of the MP3s i have. If you haven't checked out the RF PC software, it has a demo mode. It's definately not touchscreen friendly or embedding friendly (screen size is hard coded), but is very easy to use.
Do you know how to read/see the information being sent via bluetooth/com? THe RF software uses a virtual com port, so it should be similar to reading NMEA GPS data (which i've done)
Any progress on your build? Haven't seen updates at FSC for a while. havent looked there or here much lately. Saw the 360 title and hoped somebody had cracked it somehow
