We use submodules for this same need here.  If the submodule is loaded,
the code is used from that.  If not, pre-built binaries are used
instead.  These could be stubs.

When we share code with outside partners, we give them access only to
the modules they need.

We further guard the code in the submodule by PGP-encrypting the source
files and storing them in the repository (as binaries).  This practice
lets us be more free with the repository and not worry so much that it
may be cloned well out of our control.  Storing code as shrouded
binaries negates much of git's power, but only for this one submodule. 
Our other submodules are still quite git-friendly.
