[R] bootstrapping for clustering

Dear R-listers,

Is anyone familiar with a package that would perform bootstrapping on species/site matrices for clustering ? So far I have been using the vegan package to generate trees (Bray-Curtis index), but I would like to associate a certainty to each node (similarly to a phylogenetic tree).
If no package exist, I would know how to generate bootstrapped matrices of distance, but how could I plot the results ? Graphically, I am looking for something similar to what is available from the pvclust package (my understanding is that pvclust makes covariance clustering from dataframes, and it cannot be used with matrices to generate Bray-Curtis similarity dendrograms?)

Please forgive my ignorance!

Thank you in advance,
eric pante
