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
* it's all an act but hey...
