I too would like to see an "xtzinb" comand. As an alternative I am using
zinb with the "cluster" option.

Subject: st: xtzinb
Dear All,
I am trying to do a negative binomial regression. My dependent
variable is a count variable, and for almost 30% of the observation the
dependent variable is zero. I have a panel dataset, therefore I am
using xtnbreg. However I couldn't find zero inflated negative binomial
regression possibility for panel data, what would be more appropriate
given the large number of zero observations. Does anyone know about
the existence of "xtzinb"?
Thanks,
Miriam
