Wrapper to download databases (was: Sharing a subdirectory of /usr/share between multiple packages ?)

I'm curious: What kind of wrappers are you using?

I'm currently packaging some neuro-imaging tools which have source
tarballs of several 100 MBs, but the actual code is only a few
kilobytes, the rest is datasets. To me it seems to be a waste of
space (in the archive) to upload theses huge binary datablobs.

I'm currently testing the possibility to download these datasets from
the package postinst script. I adapted the scripts from the
msttcorefonts package (in a simpler form).

This has the advantage that the datasets are only downloaded if it is
really necessary (there are modifications checked by md5sum). The is
especially usefull as the datasets tend to be the same across releases.

Are you using a different approach?
