OpenAFS sounds really interesting - but only based on what you've said
here.  I've looked at the OpenAFS site[1], and the (scant) wikipedia page on
it, and I don't see any description that comes even close to telling me
*what* OpenAFS does.  Your paragraph here is remarkably succinct, and I'd
like to learn more of what OpenAFS has to offer without reading through
installation documentaion or trying to distill info out of its maillists.

Do you know where I can get more overview-type information?  I'm really
interested in exactly what "offline access" and "cached" files means.
In the best of all worlds, it could be really useful for disaster/emergency
planning (eg, if the connection to the file server is severed).

[1] http://www.openafs.org/ - If openafs has an "overview" or a "Why OpenAFS"
section on this site somewhere, it's not at all obvious to me.
