Looks good to me, and certainly something worth being added to R.

2 quick (related) comments:

1) I am not sure if we want to include links to the Latex-Sources by
   default, those might confuse unsuspecting novices a lot. Perhaps
   make those optional using an argument to browseVignettes(), which
   is FALSE by default?

2) Instead links to .Rnw files we may want to include links to the R
   code -> should we R CMD INSTALL a tangled version of each vignette
   such that we can link to it? Of course it is redundant information
   given the .Rnw, but we also have the help pages in several formats
   ready.
