This is the way I would look at doing it:

Lets say, for example, we have a bunch of buildings linked via a low 
bandwidth link, so each building is on a different subnet and traffic 
over the links is at a premium.

I would place a master server in each building, and each building would 
have it's own dns server. The main building would have a primary 
cfengine server, as well as a secondary (if it needed it on that site).

The DNS server on each site has its own local cfengine server as a 
static (CNAME rather than A perhaps) entry, but it is the same name on 
every site (but depending on which site you are on, you will get a 
different IP address when you resolve the name).

Then in order to get the secondary servers to update from the primary, 
you just set the secondaries to resolve to a master DNS server in the 
main building, which resolves the server name to the primary cfengine 
server.

Does this make sense?

Marco.
