Re: Depending on Microsoft..
There are enough Linux worms and exploits around to not guarantee security. It's feasible that a bug in an NFS implementation could have a similar to effect to the one in Windows' CIFS that "caused" this. You'd also need to get the vendors to release their software for Linux.
Linux is my OS of choice at work (HPC), but I can see that it's not appropriate for all scenarios at the moment.
