MultiGrid for Navier-Stokes Eqns-What's current status?

I would appreciate hearing from multi grid and/or CFD experts
about the state of the art for multigrid for solving higher order
discretizations of the nonlinear , equilibrium incompressible
Navier Stokes eqns. For example, if using the Hood-Taylor elements
for a finite elt discretization, what is known about the convergence
properties of various nonlinear mg methods? I'd like to understand
what's proven in full rigor, what's almost certainly true and has
a lot of mathematical support, what's believed to be true and what's
believed / observed to fail. This is a lot of detailed questions,
so I'd appreciate just pointers to recent work in these directions.
{Of course, like most people, I'm specially interested in the
dependence on the Reynolds number in the above issues.}

Thanks, in advance,
Bill Layton
