Write an export HID. It's the same way we export gerber and
postscript.
.dxf would be very cool... but having been fooling with .dxf lately, i'd
hhmmm... QCAD only opens .dxf, pstoedit only opens PS, not EPS. But I
guess if I don't do 'fill page' I should be OK.

Oh, right. EPS, not PS output. Both are Postscript, and thus
rasterized, but the PS output may be scaled to fit

So, did this keep the stroked vectors nature of the data, or rasterize
it finely?
Keep it vector, and either

The advantage of going pcb-dxf and not gerber-dxf is that you only
have to worry about supporting the data we have, which is
significantly simpler than trying to support a generic gerber file.

Oh yes, I hear that. What's easy and what's most generally useful
seldom overlap.
Is there any free (as in speech) software that will convert gerber to .dxf?
Reason: I have access to a laser cutter through the TechShop and am
trying to work out a path to cut el-cheapo solder paste screens in
acetate sheet or similar material. I tried the path of creating a
PostScript
of relying on the check plot and the inherent precision limitations
of PostScript. Or perhaps I underestimate the check plots?
PCB's Postscript is stroked, with as much resolution as the gerbers.
They should be fine, as long as you don't rasterize them during any
interim steps.

PCB is free, and it'll export .eps. It's not a dxf but perhaps your cad
application can import it. You'll have to give it a scale, but if
you're clever here, you'll never known the difference.
Has there ever been a discussion about exporting hard cad files from PCB
... such as dxf or even a closed proprietary format?

PCB is free, and it'll export .eps.
Oh, right. EPS, not PS output. Both are Postscript, and thus
rasterized, but the PS output may be scaled to fit on the page. If
you don't select the fill page option it may still work (with an
offset or rotation) but the EPS is a better choice.
