[R-sig-ME] Could lme4 fit a nonlinear mixed effect model using AGQ?

[peter zhang]

I wonder whether lmer or nlmer could be similar to NLMIXED in fitting a general 
nonlinear mixed effect model by the ML approach with AGQ. It seem Bin Bai only 
implemented it for some specific models in the summer of 2008. So I wonder 
what's the development at this stage.

Thanks,
