Ok, i should probably just edit the first post... but would love to see this tested....
Ignoring the previous hack, the more open Flash-Air system seems to be the way.
Required:
A flash-air SDHC card
A pc or computer of some kind
The ability to synchronize (And check if available to synchronize. This could and should be possible using most syncing tools...)
The distance may be an issue, i've just double checked, and outside my house, my SD card slot is about 8ft from my router.... So i should be ok.
Some geeky know-how or will to win may be needed.
http://www.extrud3d.com/flashair - attached python script to test.
So in theory... just to test this process, we need someone with a flashair card, and the ability to run the python file (Add a few mp3 files into a folder etc... - go and check the car).
From there, we setting a timing check and send python script. (Could easily raspberrypi-this, so not to hang a pc/computer up)....
Once that is working, should be really simple to bundle up some instructions for all to use

w000p!
(Ok, no cash till end of jan as xmas killed me, so i'm gonna have to wait a while!!)
