lmer and autocorrelation structures

Dear mixed-modelers,
I'm interested in modelling a dataset using generalized linear mixed models (specifying "family=binomial" with random effects) in which there is temporal autocorrelation in the response. Is there a way to do this in the new lme4 package? I've used the "correlation" argument in the nlme library to specify a correlation structure for least-square means regression, but this option appears not to be implemented in the new lmer call in the lme4 package. Is such a thing possible (and appropriate) at this time? thanks,
Possible, but only in the fortune("Yoda") sense. In other words that
capability is not built into the lme4 package.
I don't think we can comment on the appropriateness of the model
without more information and perhaps a look at the data. However,
until someone writes the code to incorporate an autoregressive
structure into lmer, the question is moot.
