package collection

As I understand it, a package collection, like http://hackage.haskell.org/packages/unstable/ has the structure 00-index.tar.gz <pkg>/ <pkgid>.cabal <pkgid>.tar.gz ... where 00-index.tar.gz tars up all the <pkg>/<pkgid>.cabal files. Such a simple structure makes it easy to add tools. Perhaps it could be made simpler by replacing the index with a file that was just a concatenation of the .cabal files with some separator (say @), and having both gzipped and uncompressed versions. The main missing piece seems to be a means of uploading packages. Any plans there? Perhaps something along the lines of PAUSE (http://www.cpan.org/misc/cpan-faq.html#What_is_PAUSE), except that we only need to upload Cabal tarballs.
