Hi,

It looks like the architecture of metering is indeed always implemented in 
similar ways. I had discussions with a company yesterday about their own 
metering implementation (which will be used in production soon) and it also has 
an architecture matching what has been proposed so far in ceilometer. I added a 
few points to the architecture chapter in the wiki:

http://wiki.openstack.org/EfficientMetering#Architecture

including a note summarizing the conclusions of the discussion regarding need 
for an independent ceilometer agent in addition to the existing meters provided 
by the OpenStack components.

What do you think ?
