I am.  I've found the Phidgets boards to be useful.  Since they are
USB, you can just throw a hub in there and scale easily.

The really nice thing is that they have a Python API (among others),
which makes it simple to integrate with manufacturing tests.  wxPython
is a good gui toolkit to use.

My suggestion would be to minimize keyboard/mouse interaction to avoid
operator error, do your products have a barcode that could be scanned
to determine model / configuration?
