What do you have in mind?  I have some US macro data in there at the
quarterly frequency.  I would like to get some higher frequency
finance stuff.

That'd be great.  There are some utility functions and templates so
adding datasets is easy, so let me know when you have some data and I
can walk you through it if you need it.   It should also be documented
in the updated datasets proposal.

The license is the rub.  Mostly I've contacted the original authors
and have had no problems getting expressed written permission for
reuse.  Authors have told me that I am the only one who has ever
asked, including datasets that are included in the R datasets library
and other packages, and I've never gotten a straight answer on the
licensing of datasets in R.  Other stuff is often public domain.
