The problem with multiprotocol filesharing has to do with the differences 
between locking mechanisms in NFS and CIFS when two users are accessing the 
same file simultaneously using the different protocols.  If your kernel and 
samba implementation supports CIFS opportunistic locking, you shouldn't have 
this problem...

This feature has been available for some time on proprietary systems like 
Netapp Filers and some commericial *nix implementations for some time, so it's 
pretty mature and fairly common practice these days.
