[Info-vax] Wide area cluster, metro area network, seeking info

Before going into the technical details, wouldn't it be interersting to
know what you want to achieve, and discuss whether clustering is the
best way to achieve it ? I, for one, would be interested to know why 
you
believe that clustering without shared storage can be more beneficial
than simple networking.
