Yes, this functionality is interesting... but: Please! No! Not those idioms! First, you can do this in the browser implementation. I think Spyglass and Verity do this already: they just use the CD-ROM as a cache. To fetch http://www.foo.com/bar/baz, they first check the CD ROM's cache table. If it's there, the get it locally. If not, they attempt to go the net. (Maybe they do if-modified-since queries sometimes... anyway...) The point is that you can get the behaviour you want without changeing HTML, if you control the browser. Since you're talking about features that aren't in the installed base of browsers, you're going to have to do that anyway, for a while. But the business of describing replicas and other interesting sorts of link info in HTML is useful in many other situations. It's seen as "the missing link" in the format negotiation strategy, for example. I don't really have time to explain fully, but...
