Let me add a bit to what Dan has said (which is all quite correct).
First, we use our laser in almost exactly the same way that you might use the Eggbot: We do all of our design work in Inkscape, and then open it up in Corel in order to use it as a “print driver” for our laser. If Corel is the flavor that you prefer, this certainly will work the other way for you.
Second, if you can describe a good G-code workflow for us and provide some example output files, we can probably write a converter or driver (like Dan was describing) that takes G-code as input to drive the Eggbot directly, without using Inkscape. While we do use CNC tools extensively at our shop (CNC router, laser cutter, vinyl cutter, computer-controlled embroidery machines), none of them actually uses G-code, so we don’t presently have that workflow.
Third, we are presently working on some new stand-alone software (that initially will just drive the WaterColorBot), that will work as a stand-alone driver for the Eggbot as well, starting from existing vector artwork.
