Unfortunately I no more use Subversion.
Do you plan to add full support to other VCS, or should I switch to a
setuptools fork?

Is it .egg-info or .egg-link ?

If it is an .egg-link, then this could be copied as with normal eggs, of

I tried right now, and it is possible to specify a relative path in the
.egg-link file.

What do you mean by "first"?
