It definitely looks like it is. Well, though it could definitely 
benefit from direct support in the database management systems. 
This DBMS support may be exactly this "something really new
and novel".

And directly comparing the number of nodes with Beowulf-style
clusters is not fair. The Beowulf clusters can be reasonably
efficiently used only for a very limited class of problems
with very high parallelism of subtasks, high computational
complexity of each subtask and very low interactions
between them. So they are a quite degenerated case and pretty 
useless for business applications.
