Well SVN is on the table too:

EESCHEMA --> LIBRARY --> (SERVER or BRIDGE) ---> REPO

SERVER or BRIDGE is located possibly on your computer or shared on the
web, say like a websvn kind of thing.  We only need a read only
interface for the kicad supplied components.

The LIBRARY is basically a "cache" of components consisting of both
their A) parsed/binary and B) un-parsed/s-expr forms.
