Does python have the capability for driver development ? Maybe with ShedSkin

     With the CPython interpretive system, it's not likely to work. But
using ShedSkin, which generates hard machine code, it might be possible.
The main problem is that Shed Skin uses a garbage-collected environment,
which few kernels have.

     Under QNX, which is a a real message-passing operating system with
all drivers in user space, it should be possible to write a driver in
Python.  There's Python for QNX.  It would probably be too slow to
be useful, though.

     I've actually written a handler for Baudot Teletype machines in
Python.  See

     https://sourceforge.net/projects/baudotrss/

Those machines are so slow (45.45 baud) that Python isn't the bottleneck.
