Using selectors with Lingo

[Jason Dillon]

Is there any way to control the message properties and selectors used  
for Lingo proxies and service exporters?

I want to setup an exporter which includes a selector which only  
accepts messages from a UUID which is generated by a component.  And  
I would like to be able to set a property on a message with the UUID  
to direct an invocation to that specific service.

How can I do this with Lingo?
