Instead of adding such functionality inside gschem, we can do the work
of creating a workable API for gschem actions first.

We could make it so you start gschem from an
outside project manager app and it gets results from beyond-graphical actions
from the outside program and does cross probing.  All with gschem remaining graphical only,
but controllable and communicating with external apps.

Sure, it's hard work.  Sure it deserves a little money compensation for tackling
such big jobs.  The linux fund doesn't seem to promote very well for getting tasks paid for yet.
Has anyone looked at kickstarter.com with funding gEDA development in mind?

I think it could work.  I'll be testing out funding some open hardware projects via kickstarter
and keep you posted on this list.
