SOA and the Single URL

["Bullard, Claude L (Len)" <len.bullard@intergraph.com>]

The subject reads like a late 60s skin flick, but 
the question is, given an Enterprise Service Bus 
and an SOA, should one use a single URL to identify 
multiple processes? Yes, I know what a dispatching 
service is, but given REST vs SOA, what do you think 
the consequences of a single URI approach are?
