Lemme hear the word s*e*c*u*r*i*t*y here. I have no trouble with your 
suggestion as long as it is as secure as TLS (ssh). Is there a secure 
precedent for configuration file URL's?

If you think I am being paranoid here, you should see the comments from 
the reviewers of the proposed SNTP RFC. Four paes of tiny text, 90% of 
which is on security.

If you want a common configuration file from a local server, mount 
/usr/local/etc from a server machine as we do here with several hundred 
clients. Almost all of these use multicast.
