Ok=2E  I also design things that go to space, but I think about this differ=
ently in that if the boards aren't using the same parts, I don't even want =
to pretend they're the same=2E

And I use light symbols for almost everything in a schematic and do late b=
inding of everything but footprint and value, so I suspect we'd get along f=
ine working together once we agreed on a vocabulary and workflow for the ta=
sks at hand=2E=2E=2E  ;-)
