I think if the nesting is because multiple measures were made to improve the measurements rather than estimate variance components, I would just mean them and use fixed effects oneway ANOVA if I wanted to use Dunnett's procedure for comparisons with a control, or Tukey's procedure for all pairwise comparisons. There are so many of these procedures (all seem oriented to fixed effects ANOVA), that I have also just used the full model error in pairwise comparisons and adjusted by Holm's sequential Bonf. procedure.
