That's great. Just a second before I sent further comments :-)

As far as I understand, this is done in pcb on a different level:

http://pcb.gpleda.org/pcb-cvs/pcb.html#Vendor-drill-mapping

Didn't test it yet, though.

If there is no "outline" layer, yes.

Sure, go ahead and create it. You create layers somewhere in  
preferences. I hope the exporter's behaviour is correct for both,  
adding the outline layer to the component side as well as adding it  
to the solder side. In the later case, general milling is mirrored,  
just like isolation milling.

Not that mirroring an x-y-aligned rectangle changes anything, but  
with some luck somebody will find the time to implement milling of  
complex outlines one day.

Yepp, that's on the to do list. Five feedrates: isolation milling  
approach, isolation milling work, drilling approach, general milling  
approach, general milling work. Many tools prefer different feedrates  
for vertical vs. horizontal movements.
