Servers can talk to each other via the dblink () function
[new in 7.3 I think]

However, Horst has described German hospitals that have installed 
physically separate networks for different computer services, so 
even dblink would not work. 

So in this case you are right: the inference engine has to run on the client, 
with
rule-originating queries flying back across the network: a potentially 
significant 
and pointless speed penalty for the poor GP with aging hardware. 
(I'm sure we've had this discussion before....)

It's all in Python either way, so I think we can cover both bases
easily.
