Go for it. 

After roughly a decade's work, and around four or five different attempts, we
now have an archive for 'apt-get r-cran-$ANYTHING' for Ubuntu (that is,
Michael Rutter's PPA on launchpad covering different Ubuntu builds) as well
as one for Debian (that is, Don Armstrong's debian-r.debian.net covering
Debian testing and now stable as well).

So it can be done, but there is a lot of detailed work underneath it. And
it's nice to have, especially for clusters as it minimizes per-node work and
keeps them in sync.

And it all started with the cran2deb work we did based on Albrecht's script
written initially for ... OpenSUSE and then ported to Debian. What goes
around comes around.
