Not yet extensive 'real-world-usage-experience' but from what I have learnt and seen myself, DLM (Distributed Lock Manager) coming with GFS v6.1 (Global File System) does quite a nice job. However, it is not NFS and requries quite a bit more pocket money to setup as a SAN is required (unless you use iSCSI served off a spare box...). So building a reliable lock manager over multiple systems can be done. Kurt
