is this basically a gerber format and if so, how does it differ from the 
current gerber export

Actually, this means export to gcode.
Brendan discovered pcb2gcode that we might be able to incorporate:

"Including in fritzing would be pretty easy as it's all written in C and 
only depends on libgerbv.  The project is also actively maintained.  It 
appears to be GPL-2 licensed which also works for us but we should sent 
them a mail as I could not find the normal GPL boilerplate in the SVN or 
the source tarball."

Another alternative could be the FabLab toolchain: http://kokompe.cba.mit.edu/
Seems to be open-source, however its license is limited to non-commercial use.

Changed title: export to cnc (and other formats)

Perhaps I should encourage you a bit :-) Export to G-code isn't that difficult. 
gEDA/PCB does it in a couple of simple steps:

- Draw the design to a (memory based) PNG, blown up by half the cutting tool 
diameter. Code from the PNG exporter should do that fine.

- Convert this to a bitmap for potrace (http://potrace.sourceforge.net/). 
Simple pixel copy operation.

- Run potrace over it's bitmap and catch the output. gEDA has tweaked potrace 
for writing G-code text instead of SVG text to do so.

- That's it!

If you look at gEDA/PCB's source code 
(http://git.geda-project.org/pcb/tree/src/hid/gcode/gcode.c), you'll see some 
80% of that code is just about writing file headers and footers, about PNG 
writing, user definable milling depths and other non-essential/easily writeable 
stuff.
