You don't really have to have networking or files to write programs. Currently in a baremetal embedded system (I am including the RTOSes) you can write programs in C or C++. It would be very useful to be able to write programs with a main() function using python. You could write an interactive shell, device drivers, even a small operating system. So what I mean here is instead of aiming for applications, you could use python to write system software.

I think there are already lua interpreters ported in this way but python is more common and perhaps easier to use.
