Yes - that is an additional problem.

If I may expand the usecase just so it's clear (and to check we're
talkiing the same language)

I do something like
$ git remote add fred git://fredcomputer/superproject/.git
$ git fetch --submodules fred

And when the recursive fetching enters a submodule, it is trying
itself to do something like
$ git fetch fred

At which point
1) the submodule also has a remote specified for fred. In which case
it can continue
2) the submodule doesn't have remote specified for fred. How to solve
this case? (I.E how does 'my' git 'discover' where fred's git
repositories are for the submodules?)
 a) By getting some information from fred, either in *Fred's*
superproject .git/config (or some other readable file)
 b) By reading some information out of the superproject .gitmodules
that has been fetched from fred
 c) By calculating a relative URL based on the supposition that fred
has working copies laid out in the filesystem.

I was tentatively suggesing (c), with a backup of (a) for the minority
cases where you weren't pulling from a person but from a mirror or
something. Having the client edit config files just feels like a hack
to me, regardless of whether scripts are enabled to do it.
