Mplus will do that sort of model with ease.  I imagine you could get at it with GLLAMM, which is an ado for stata.  See:

http://www.gllamm.org/

And if you work out how to do it, I would love to see the code.

LIMDEP is the only software application that has a procedure for ZIP/ZINB 
for panel data. It is not accessible using the menu system though. You must 
estimate it using the command line.

This question has been asked a few times before on Statalist.
Unfortunately, there is no such Stata procedure (at least that I am aware 
off).

One solution that has been suggested before is to use the ordinary zib
with the cluster-option and cluster on your case ids.

Best,
Johan Hellstrom
