I had tried dabbling with openafs some time ago.  I think it is
read-only if the master repository for any particular set of files is
not accessible.  So, you need a master online at all times.  However, it
is distributed which speeds file reads, and it provides redundancy.

Also - it seems like it isn't really well-maintained unless something
has changed.  There are a TON of docs for it - but it seems like it was
a project that got intense attention and then just was dropped.

However, I haven't touched it in maybe two years so perhaps something
has chanted.  If OpenAFS is active again it is the sort of thing that
would certainly be worth a PLUG talk.
