In addition to the previous suggestions, you might also have a look at the 
following paper:

Kelvin K. W. Yau, Kui Wang and Andy H. Lee. Zero-Inflated Negative Binomial 
Mixed Regression Modeling of Over-Dispersed Count Data with Extra Zeros. 
Biometrical Journal 45 (2003) 4, 437–452

The authors have written R/Splus code (available from them).  Although the 
article is focused on ZINB models with random-effects, the code will fit a 
NegBin with random-effects (if memory serves).

Hope that helps.

cheers, Dave
