Henry; The implementation explanation was not clear because I am not sure if it would do what I was thinking. I was thinking that I would use Coda to cache read-only media (CD-ROMs) on the client side as Coda does from the media server (Coda server and SCM). However, the server and client would be the same. Thus, a media server would have dynamic caching if you will and the user-level security of Coda going for it. However, in this context, I think Coda may be a little "heavy" for such an implementation. It just seemed like a good possibility to use Coda schemes tailored to a different use where there could be a heterogeneous network.
