R help - Jan 2005 - glmm multinomial?

I'm looking for something like Brian Ripley's glmmPQL that will handle 
multinomial data. Does anyone know of anything?

Thanks,  Ted.

It's a lot more complicated conceptually.  A multinomial model has K-1 
linear predictors which should probably have a correlated joint 
distribution.  We don't even have software for multivariate linear mixed 
models, AFAIK.

Would a surrogate Poisson model be good enough? glmmPQL can fit those.
