Linux
when i say "linux" i regard to these chips i mean that the operating system on the player itself is linux. Have you ever seen linux for ipod, this would be the same
they would use linux, albeit very stripped down version, to produce all the GUI and applications on the player. this means that the potential to create custom applications for players using these chips is possible, not just that, once the open source community get involved almost anything could be added to the players
im not sure if the chip in your is running linux but actions also have 2 more chips in the mix which do run linux - to what extent i dont know, wwe will have to wait and see.
if you wonder over to the linux ipod page and have a look what has been done there and just think that maybe the new actions chips could be added to / customised in the same way

these are only thought and ideas at the moment and who knows what will happen, maybe none of this is possible, we will have to wait and see
the link below shows a little info on the actions
2137 (next one up from Daremoses) and mentions linux here (just so people dont think im going mad!!)
