I know that there was some initial work with NFSv4 and caching at the NFS level. With AFS support dwindling, some AFS proponents are saying that NFSv4 is the replacement. File caching with NFSv4 may be another way to do it.

It's funny you should mention CODA. I've just recently started looking at it as a way to get davfs mounting support onto Solaris. It's not been easy. The CODA Solaris kernel module is several years old and looks like it hasn't been touched in at least 2 years. It does not cleanly build on svn_50. CODA itself has issues as well. CODA certainly looks like an interesting option as it makes it very easy to support filesystems under Solaris (we *still* lack smbfs for pete's sake) It seems like lots of work is going to be required to make it useful however. NetBSD 3.1 is currently getting installed on my Ghetto Laptop, at which point I will start playing with CODA. If I like what I see, I'll probably look into spending some time trying to at least get the kernel module working. -brian -- "The reason I don't use Gnome: every single other window manager I know of is very powerfully extensible, where you can switch actions to different mouse buttons.
