I have been looking into this myself, over the past couple of weeks.
I will gladly contribute my macro package, when I have a few loose
ends tidied up -- I already have bookmarks working, internal references
almost so, and a basic manpage on the way.

I had a look at this, and have drawn inspiration from it, along with
more recent discussion on the list, initiated by Carlos J. G. Duarte, in
the development of my own package.  IIRC, Kees' macros were undocumented,
needed to run in unsafe mode, and hadn't addressed the issue of computing
bounding boxes for link hotspots.  Carlos tackled the bounding box issue,
in respect of internet URI links.  My intention is to consolidate all the
features in a single core package, eliminate the requirement for using
unsafe mode, and to provide some documentation.
