The advantages of having the data on CPAN is that the entire module is self-sufficient and widely mirrored. It makes it much easier to install, and if you have a CPAN distribution on CD or in a local mirror, you have everything you need. The disadvantage is that it takes up 480K on every single CPAN mirror.
I'd be more concerned about the updates. Make ::Data subdistro of it, like brian d foy has done with Business::ISBN and Business::ISBN::Data. When the code updates, you don't have to push out half a gig again. Code and data are separate distros.
