I think I mean you could mark a repository (such as an a  filesystem, 
ssh or http repo) as available when a system is offline. When there's an 
offline build, the stuff in cache is always there, but you'd only hit 
those repositories marked as available offline.

the other trick is to hit every HTTP repo with a GET request on startup, 
but that can be misleading. the ibiblio root is dog slow, and proxy 
servers can lie, returning an old copy, even when the repository is missing
