I have no idea what Gcode is or is used for but looks interesting.
I was talking along the lines of the silhouette Cameo or the Phoenix Silver Bullet cutters that use .svg format but maybe support them in having direct linking to the cutter driver (currently Sure Cuts a Lot 3 (Scal3), Signcut Pro or Make the Cut (MTC))
also being able to import/export embroidery files would be very, very cool as a lot of home machine embroiderer's would be able to design their own files or adapt svg's for converting in the machines own software (like embird)
