That alone is a great idea :-) For projects with shared access, that's
more or less mandatory if you want to have any kind of oversight of
what happens between revisions.

Stepwise refinement ist also a concept I like. Do you envision that
a GUI user would still find it convenient to make full use of the
potential of this system ? Or would they have to switch to a text
editor for some things ?

How would the "pinning" of a component you reference occur ? E.g.,
would it be  (interit FOO)  (with the pinning completely external) or
more like  (inherit FOO-rev12345)  or perhaps  (inherit FOO (origin
dicks-bazaar.org/parts/comm/gsm/amp/ 12345))  ?

Hmm, why the TCP bridge ?

In general, I'm all in favour of making KiCad aware of revision
control systems. In qi-hardware, we're working on implementing
graphical revision histories and a large part of the work is to
just deal with all the small mistakes people make when committing
things. If KiCad could take care of, say, marking files for
committing, that would eliminate the need for quite a few dirty
hacks. Similarly, we haven't run into problems due to the current
lack of pinning yet, but I'm sure we will.

So, I very much like the direction in which you're thinking of
taking this.
