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.
