Not sure if this has been mentioned, but a previous mod implements redstone and other world interactions via the serial port of the VM. Other options could include listening for web requests to a specific IP/Port combo. In either case, it'd be really useful if the VM could execute command-block commands.

Great idea. I'll add this later.

if this gets implemented, I'd def be happy to set up a Python API for it. Ideally it'd be something platform independent, so that it doesn't matter if someone is using Win98 or Arch Linux.
