Yep.

That (2010 timeframe) is pretty new in the VMS world (8.4 was released 
in 2010 I believe).

But that (release was January 20th 2009) is actually pretty well established
in the Linux world. RHEL is at 9.0 / 8.7 today. And 5.x is long out of
support.

But that is because the IT world today use databases with
their own sync mechanisms not file system with an OS
provided DLM.

The demand is not there.
