While angular momentum is extremely important for simulation of 500,000-Sun BH's, I seriously doubt that quantum mechanics are either modelled or have any effect on BH's of this size. I know it isn't modeled and I agree it wouldn't have any significant effect.

I understand why LIGO wants to do this: because they want to learn what to look for in gravitational waves so they can win a Nobel prize for "seeing" these gravitational waves.
But my interest is completely different: I'm interested in learning about completely new solutions to the GR equations.
There's a guy at Cambridge Univ. who's been doing some of the best N-body simulations; I'm going to try to ask him what the current state of play is.

Except we don't know the equations of quantum gravity. So we could only simulate the GR collision, which for smaller BHs we're sure leaves out important stuff. The LIGO project has already done a lot of simulations of realistic mass BHs colliding - although I don't know that they've considered near light speed collisions.
