May I ask where I can read more about this? There have been a few ideas
thrown around for how to do this with OpenAFS, but I'd like to see what
others are doing.

When I last looked at it, the Solaris FUSE implementation was written
only for OpenSolaris. It generally worked for me on OpenSolaris, but it
seems to be a rather unmaintained project for them. With the OpenAFS
FUSE client, I needed this patch to be able to see changes to files
originating from other clients:

from the Coda/AFS side is probably possible, too, though.

The MacFUSE project seems more active, though I never tried to run the
OpenAFS FUSE client on it.
