Open Source Optimizer
It might be nice if OpenMx came with an optional open source optimizer. There are a couple that can deal with nonlinear constraints: solnp (R package Rsolnp), and DONLP2 (R package Rdonlp2).
This is not a high priority and they would probably slow down performance, but maybe some users would prefer to use an open source optimizer.
