For the NETSim product (Ericsson-internal link: http://internal.ericsson.com/page/hub_radionetwork/unit/pdu_gran/sim_products/netsim/index.jsp) we have solved the problem in a radically different way. We ship two Erlang runtime environments with the product (one for Solaris and one for Linux) so that it can be installed and executed on a network of mixed architectures.

For each new OTP release we run a script which makes a run-time package out of our installations (by removing source code, documentation and applications we do not need).
We then integrate the run-time package into the product.
