I've considered that as well (on my CNC Taig), but haven't gotten around 
to trying anything other than using it to drill the holes.  Having done 
a number of boards with chemical etching and knowing how simple it is, I 
haven't gotten up the initiative to try milling one yet.

If you explore the option, would you mind posting details here?

Thanks
