Well, if you are going to serve in a format that is distinct from what
is actually used on the physical media, why not just provide servers for
multiple formants - 9p, nfs, smb etc..
I think there are some network enabled external drives that already
do that (maybe not the 9p yet)..
Of course if you are backing up filesystems, then you still really need
a the media and served formats to be capable of preserving all relevent
metadata.
I encountered this most recently on a project where I was developing
an embedded Linux application for a client whose development environment
was exclusively Windows cross development based. I developed on my Linux
laptop, but they wanted the kernel source tree checked into their surround SCM.
I tried using samba to copy the tree to windows (which hosted the surround
client) but of course it failed after about half an hour due to some
incompatible file names. Trying to check in a complete vmware image
exceeded the maximum file size, and in any case would have defeated
the revision management capabilities. Any renaming of files would have
broken who knows how many parts of the convoluted set of makefiles
and scripts.
If you only care about the contents of a modest number of files,
interoperability isnt such a big problem. If you want to be able
to make accurate backups of entire filesystems then it gets hard
if the target is not a natice filesystem format.
