Yes, that's an idea. I'll probably get the modules panelized (if that's
the word) from some boardhouse anyway. Now, what I forgot to say, was
that the actual firmware on each module will not be the same from one
module to the next. Well, a couple could have the same code, but it
will vary a lot. If things work out as planned, they will be sold in "sets"
of, let's say, 10-20 modules (together with a separate power supply
module), each with separate firmware. If I prepare 10 sets at a time, 
I could of course program 10 similar modules at the same time also...

This is going to be a simple "office-desk" solution.

Thanks for all ideas !
Jan-Erik.
