I have played around in the past with some ideas for using a battery of SA
minimizers. If I recall correctly, this gave some improvements in getting to
the neighborhood of the global minimum, during the early part of the
iterations, but convergence in the later part was no faster than the public
version. 

An obvious way to do some parallelization in optim would be to do numeric
gradients and/or Hessians in parallel. That would be a generic, general
purpose improvement.
