I'll try and read through that but I was thinking of something at the 
top level which emphasised that it was running on something behaving as 
"a computer" rather than "an appliance" or "something requiring 
cross-development".

Well, provided that we don't get into "distro wars" I'm sure limited 
comment here is acceptable to the list owners since such a thing could 
also be used for local SVN and so on. I can't speak for the device 
mapper but I've had no problem at all with NFS on a Slug running Debian 
"Lenny"- just install nfs-kernel-server and set up /etc/export.

I think that the one thing I'd caution is that NFS is poor at handling 
symlinks, and I'm not sure where it stands on locking. If you have a 
server setup that uses symlinks or a client app that requires locking 
then it might be safer to consider other options [waves hands in air] 
should they exist.
