For now the script runs on a computer and transmits the files to the device using wifi or a cable but there isn't really a reason why it can't run on the device. I do plan on making something like that work on the device eventually.

I'm pretty sure it's a Yocto based Linux image based on the toolchain they distribute.

Thanks.

What's the WiFi transfer mechanism? Push or pull?

For now the computer pushes to the tablet but it would be simple to write a program to pull.
