Cool.

    Although it will be hard to decide on the defaults

Well, this is nothing for right now, but my opinion is that every link
should be the same color by default, and the color should be
sufficiently dark that will not print as a light gray on b&w printers.
Here is one dark red color like that:
  \definecolor{refcolor}{cmyk}{0.28,1,1,0.35}

    I am not sure there is a package for PDF, 

Well, standard transformations can be done with the basic latex
graphics/graphicx commands like \reflectbox.  They work with all the
usual drivers.  An implementation for (e)plain sound good -- if it
doesn't already exist.  Seems like it should.

    Maybe a similar script (or maybe even a C program) will have to be
    added to Eplain?

Whatever's needed.

    should specify count of _immediate_ subentries this entry has.

Yeah.  It's a big pain.

    Any ideas how these problems could be handled best?

I'm not entirely sure what you're asking.  Since the different systems
handle bookmarks in different ways, we're stuck with it.  

I think bookmarks are pretty much a separable issue.  Making links for
equations and cross-references seems like a good first step.  Or how
about just explicit live url's?  That would probably get far more use
than anything else, although it's not easy to implement and is kind of a
separate issue from the internal references.

Best,
Karl
