Using zeroinfl on panel data

[lukaskawerau]

Is there a way to run zero-inflated negbin models on panel data? Using pscl on cross-sectional data works a treat (thank you for the package!), and I'd like to use it for some panel data I'm working with as well. But so far I haven't found any implementation and am starting to wonder if it's even possible in principle. Any ideas where I might find something on this?
