Hmmm, so what is your exact suggestion for our numbering scheme for released 
versions and snapshot versions?

Using released packages only for Hugs releases is a good thing, although GHC 
and nhc98 are not doing it currently (at least not via their scripts, I 
suspect that there is some manual intervention). I am not exactly sure how to 
handle this: Should we have a table of explicit package versions to get, or 
is there some canonical URL for the latest released version of a package?

And how exactly should the sharing work? And what about nhc98?

Exactly this "bit of extra effort" is unclear to me, so I'd prefer if somebody 
else would do the conversion.
