The basic idea is to be able to easily use overlays (without layman). I believe this to be a pre-req to the "Cache Sync" idea listed on the wiki.
each repo should be able to have a differently defined way of sync-ing (within predefined standards), I think they should also be capable of defining the way that Manifests are handled (I don't think git needs more than distfile manifests, other vcs may be similar). Supported repository types should include rsync, git, svn, hg, bzr, darcs, cvs. each SYNC_METHOD should be isolated from the others in code so that they can be improved/extended easily. comments, additions welcome -- Caleb Cushing http://xenoterracide.blogspot.com
