This is interesting. However BeleniX is not bandwidth starved, it is sitting on a high-powered server and high-capacity pipe at Genunix.ORG :) It is the downloaders who can be bandwidth-starved. Even rsync can be used for this purpose. It is extremely efficient in calculating the diff blocks. However one more point is the BeleniX now has an almost full-fledged package manager with upgrades to new version possible a-la OpenSolaris 200x.xx. The same Snap Upgrade works nicely. Check this: http://moinakg.wordpress.com/2008/11/22/the-belenix-package-manager/ Unlike the multi-year IPS project, it took me 4 months to get to this state.
