Much as I hate* to agree with Phil I, um, do :) Seems to me that the 
agent approach is more part of a monitoring framework than a registry, I 
don't know offhand whether we're planning to include metrics such as 
service liveness and response times as transient metadata in the 
registry but that's where I'd see agents fitting in rather than in the 
initial registration.
