Eric -
I already have 10,000 (ok, maybe I'm exaggerating a little bit :) ) file
formats to convert from/to, so it'd be nice to keep everything in vt*. Does
anyone know what happened to the patches Eric is talking about (either
multiple timesteps in a vtu or "shared" geometry?) That thread seemed to die
with no resolution.

Thanks,

David
