The way that I imagine the "cache sync" idea should be implemented is like paludis's "unavailable repository" which uses of tarball to distribute package metadata[1]. The tarball approach that they use seems pretty reasonable. However, it would probably also be nice to be able to use a protocol such as rsync to download the metadata/cache/ directory from the same URI which is used to fetch the ebuilds themselves (maybe paludis supports this already, I don't know). In order for the clients to be able to download the metadata/cache/ directory, first that directory has to be populated (as is done on gentoo's master rsync server). I'm currently working on a tool called 'egencache' that overlay maintainers will be able to use in order to populate the metadata/cache/ directory [2]. It will be included in the next portage release. Before we implement something like "unavailable repository" for portage, first we'll have to add multiple repository support, and that's a decent sized project of it's own. Somebody has mentioned interest in "multiple repository support" on the gentoo-soc list [3], but they haven't submitted a proposal to http://socghop.appspot.com yet.
