Gordon:

I'm happy to do them in Protel and post them; OrCAD users can open them as well.

Let me know if I can help.

for some netlists I've been managing.  It's great to diff and I'm
working on what would be a "nightly build" concept for schematics also.
Finally, I'd like the schematic capture tool to be an independent
choice; i.e., I want non-Eagle tools to work as well.

Interesting idea:  yes, it has the netlist in usable format, but it
carries the layout positioning (including vias) and not the schematic
positioning.  I had originally excluded it for that reason, but it
raises the question whether it is nevertheless adequate for these
purposes.  There certainly could be a lot of benefit to, say, having a
capacitor forever locked next to the pins it decouples.

It is in ASCII and editable; however it carries a LOT of graphic data in
addition to the netlist in an Eagle-specific form, and that (to me)
makes the format unusable.
My thought has been that the netlist data is critical, and that position
of components on a schematic is next-most important, and that getting
lines from the pins with the net label on them is third-most important.
Actually connecting all nets that require connection is not necessary
for a first implementation of this.

Thanks--  I'm sure we will.
