At one point, the Bus ID was used in the config files for configuring bus 
level things like the workqueue and bus level interceptors.    With the new 
config stuff, I'm not sure if that's true or not anymore.       If not, how 
would someone configure those things?

Basically, if I have 5 Bus's in my application, how would I configure each one 
uniquely?

Instead of the default being "null", I would think it might be a good idea to 
keep a static counter someplace and each time a bus is created with no ID, 
just use "CXF-Bus-#" or similar so they would each be relatively unique.   It 
wouldn't guarantee uniqueness as someone could create two or more busses with 
the same ID, but in the default case of not specifying it, they'd be unique.
