[R-sig-ME] lmer: ML and REML estimation

I am writing a paper using the results that I obtained this week with
lmer (thanks Doug Bates). I wanted to clarify one technical point
about lmer to make sure that I understand its mechanics correctly when
reporting my statistical methods in the paper.
I used lmer to fit several multilevel logistic regression models. The
help page for lmer states that these binomial models are estimated
with maximum likelihood (ML) methods. My high-level reading on linear
mixed effects models has suggested that REML estimates are better than
ML estimates, I wondered whether non-linear likelihoods, like those of
the binomial models that I have used, can be estimated with REML
methods or not. If this question is obviously stupid, keep in mind
that I am just a dumb surgeon, not a statistician.
