Just to say that both Fedora-Commons and DSpace really, really need opinionated installers that make choices for the user. Getting either installed is a real struggle - which we demonstrated during the Crigshow, so please don't write in the comments that it is easy, it just isn't.
Something that is relatively straightforward to install, is a debian package.
So, just a plea in the dark, can we set up a race? Who can make their repository software installable as a .deb first? will it be DSpace or Fedora? Who am I going to send a box of cookies to and a thank you note from the entire developer community?
(EPrints doesnt count in this race; they've already done it)
