Any SCM worth its salt should support that.  AIUI, that's not what Tim
wants.  He wants to intermix files from different repos in the same
directory.

i.e.

project/file-1
project/file-2
project/.git-1
project/.git-2

So file-1 would be in the .git-1 repository, but file-2 would be in the
.git-2 repository.
