Prediction variance for GLMM

Dear all,


I would like to ask the following question. Is it possible to obtain prediction variances for GLMMs in the package lme4 , based e.g. on the function glmer? I know that it is possible to do it with "pure" GLM's but I don't see any options for GLMM's.  I realize there is a problem there because such a variance can be defined in several different ways...


Let me know and thanks a lot in advance!


Yours,
