Good idea.

But just what is the problem with NFS V2 under Linux? Reads are fine and the
write performance is getting better all the time - so I guess that leaves
lockd and statd - specs for which aren't freely available.

So how about we write our own lockd and statd - based on what we think it
should act like? I get the impression those two are "userland" processes -
so once the thing is made - there should be nothing to stop it also being
ported to other OSes. I hardly know squat about the internals of lockd, but
doesn't it just involve client/server lockd processes talking to each other,
telling them when a local file is locked/unlocked so that the other system
can do the same? We could call it llockd and make it a new RPC program so
that other Unices could run it and still use their own lockd.
