[R-sig-ME] example of confidence intervals for predicted values?

Got an example?

I'm aware of controversy about problem of calculating CIs in glm. I'm
also aware other programs throw out CIs that may not be completely
correct.  I also understand profiled std errors for parameters and
about 60% of bootMer.

And I understand almost 0% of this comment in ?predict.merMod


     There is no option for computing standard errors of predictions
  because it is difficult to define an efficient method that
incorporates uncertainty in the variance parameters; we recommend
‘bootMer’ for this task.

Can I have a working example of how this leads to a 95% CI on
predictions from an lmer. or glmer?
