I have an old v1 Echo that I want to experiment with. Using this guide, I see it's possible to root this Echo and install a custom linux kernel (2.6.x) on it: https://github.com/echohacking/wiki/wiki/Echo
My question is: should this in theory allow anything that could run on that version of linux to run on the Echo (withing the limits of memory/processor etc)? Specifically I'd like to have the Echo automatically play sound files after it boots (without using it as a bluetooth speaker etc), which would be v simple to run on a basic linux system - is this feasible?
