intents broker == user agent ?

Dear all,

 From the discussion on this list, or the webintents.org site, or the 
chromium design document, I have not found an explicit mention of an 
intents broker entity, the entity that processes intents registrations 
and requests.
Possibly the intents broker is assumed to be the user agent.*
*Is that the only possibility, or just the most obvious of multiple 
possibilities ?

Best regards
JC
