Ha! The HPGL job was a code demo for a contract with Inkscape. Didn't 
pan out, alas. They seemed happy with the code I made for the 
interview/challenge.

So, you've got a g-code file you want to plot on one system, and the RPi 
connected to that system (serial cable?) controlling your lego based 
plotter? And you're designing the protocol to go over the serial cable?

It's perfectly possible to have a text dialogue over the serial cable.
