[Rd] alternate licensing for package data?

  Does anyone have speculations about the implications of the GPL for
data included in a package, or more generally for restricting use of data?

  The specific use case is that I have a package which is otherwise
GPL (version unspecified at present).  There are various data sets
included, but they are all essentially in the public domain.  I'm
thinking about including another data set, but the original author of
that data might like to impose some reasonable restrictions (e.g.
please don't use in an academic publication without explicit
permission ...)  Would such rules be expected to be compatible with
CRAN rules?  Will having the package be "GPL except for file XXX, see
LICENSE" mess things up horribly?

  I can of course make the data available for download and include a
link, and/or make a special package that contains only these data, but
it would seem to be more convenient for end users, and more
future-proof, to put everything in one place.

  I know I will eventually need to take this up with CRAN, but I'm
looking for reasonably informed opinions/suggestions ...

  cheers
