Is there a specific way to set a name server so that clients are always *forced* to use an autoritative name server?
UltraDNS and some others have mentioned little features they have, but it only hints at the possibility that somewhere in the DNS spec.
Are you trying to make sure that the clients do not use cached lookups? If so you could use max-cache-ttl and max-ncache-ttl with a very low ttl like 1 second. Although then you still have a problem with the client itself caching the lookup.
More such that the client can cache it, but not a 'server in between', *only* the authoritative box... Hopefully that makes sense, i'm basically asking on behalf of our CTO and just mentioned your question... The answer to which is yes, trying to not use cached lookups.... Trying to pick through the proposals and determine what it is they (ultradns and Savvis ITM features are relying on)...
