Sorry it got lost.  Your problem description is good and the question
makes sense.

If i am not mistaken there is indeed no easy solution for your problem
with current tox.  The use case certainly makes sense to me and i am
in fact using devpi indexes to solve it for myself.

To make things work locally with tox i think we would need a new option.
I see two possibilities:

- "pre_install_commands": tox would call it ahead of
  installing the package or the tox.ini-specified dependencies.
  You could call a script that (re)creates the subdirectory dependencies
  and installs them.

- extend "deps" such that when you specify a relative path to a
  "setup.py" it would package and install those.

The first solution is more general but i kind of prefer the second one
because it directly solves your problem.  However, i am not going to program
this any time soon myself unless paid (which is quite possible, i've done
paid feature additions in the past, contact me privately if interested).
