how to work with unreliable filesystems?

[Joakim Verona]

I have a smb filesystem mounted over a shaky vpn connection.
Much of the time this works, but if the share hangs for some reason,
emacs also stops responding, waiting for the share to come back.

I currently solve this by unmounting/remounting the filesystem, but
its all very inconvenient.

It would be neat if a directory hierarchy could be marked "unstable"
and using copying instead of direct writes, much as Tramp works. 

I guess this would ideally be handled at the os level, but I have
twiddled mount paramters back and forth to no avail. 

Any hints are apreciated.

Perhaps you should use the coda file system.  It's a distributed
shared file system that is able to continue to work in disconnected
mode, and when the servers recover their connectivity, they
synchronize the changes.
