As I mentioned earlier (months ago) :)
it could be a mountable fake file system.

mount special-file mount-point -t cluster-type

The mount-point would be a directory where all the 
control interfaces, including a standard subset and
whatever extensions the particular system adds on, will
live.

The special-file would contain the configuration info
for this cluster membership.

the cluster-type would be the clustering discipline to 
give the special-file to, to set itself up.  Mount might
be able to figure out what kind it is on its own.

I was about to write a completely user-mode system based
on unix-domain sockets this spring but got distracted.
