cran2deb: 1700+ new Debian / R packages

Am I correct in thinking that cran2deb is only working with Squeeze (and
presumably Sid?) at the moment and not with Lenny? If so, are there
plans to have cran2deb work with Lenny or after Squeeze is released will
that be the first opportunity for users of stable to try out cran2deb?
Thanks!
