The best option today is to run a full-service resolver on the host;
which is a tad heavy for most desktops, not to speak about the cache
misses that would cause root server system load. The latter of course
can be avoided by setting forwarders.

OTOH: A thicker stub resolver does indeed exist; lwresd in the BIND
suite. Calling it from applications does however mean using new API
calls; since the traditional resolver API is oblivious to DNSSEC.
