FWIW I already see a DoS 'attack'.
I have some filestore shared using NFS (to Linux and Solaris) and
using samba (to Windows).
I use it for release builds of a product to ensure the versions
built for the different operating systems match, and because some
files have to be built on an 'alien' system (eg gcc targetted at
embedded card).
I can't run the windows build at the same time as the others
because the windows C compiler manages to obtain exclusive access
to the source files - stopping the other systems from reading them.
