Dan,

Your description is a subset of my definition of referral. At this very 
beginning, I do not want limit us that narrow.

You have described a specific way how referral information may be 
transferred - through an existing channel between two parties. 
Obviously, there are many ways to pass the referral information. I am 
not sure we are in the stage to discuss it in details now.

If your motivation here is to simplify my three-party decription into 
two-party model for easy understanding, I can agree. But I still prefer 
to leave the referral information transfer mechanism out of the referral 
basic definition.

Try the below description:

Referral enables a communication initiator to aware relevant information 
of its destination entity in order to launch a communication channel. 
This referral information can be obtained through existing communication 
channel between these two entities or from thrid-party entities.

Cheers,

Sheng
