I've been thinking that also. To do that, what you'd need to add is:
* An additional layer.
* Ability to "draw" outside the board space. Alternately, have the
user draw the outlines and have pcb generate the mill program. I'd
rather hand-edit the mill lines, since it allows you to simulate
true-square inside corners or specify which inside radius you want.
* Filters to limit to 93/62/31 mil lines. Or at least, a warning that
you're using a nonstandard mill. We probably should have a warning
for nonstandard regular drills too.
* Hook into autoplace/autoroute/optimize.

Why not just use arcs? Excellon routing format supports them.

Postscript has this. Output can be up to 5x assuming you have the
paper for it. Perhaps a posterize option? Although there are
external programs that can do all this for you too.

That's an assembly drawing, not a fab drawing, but it sounds useful.
Another option I think would be neat would be to have PCB produce a
single PDF instead of a set of PS files.
