I would think not... my feeling is that in many cases, you need to tune 
queries and other parameters individually for each target to make up for 
small differences in implementations... this happens less and less between 
library targets, which are slowly aligning to their respective profiles... 
but any kind of cross-domain searching usually requires a certain measure 
of intelligence on the part of a the client.

But I *am* looking forward to a discussion about parallel operations and 
the asynchronous interface in ZOOM.   :-)
