The one current limitation that VisIt seems to have compared to
Paraview is ubiquity.  When I wanted to play with the latter, I found
it in the Fedora repos for home and it was in Ubuntu for them to
install at work.  There's a lot of people interested in VisIt on
Ubuntu, but the thread I read suggested that the only volunteer
packager wouldn't be able to work on it for another month.

If our VTK IO isn't as fully compatible as the Exodus IO, though,
that certainly counts as a point for the latter.

Speaking of higher order elements and available visualization, do any
of these viz programs actually support *high* order elements?
Quadratics don't count.  I remember one of the problems I had with p
refinement in libMesh was just getting a good look at the output...
