Yup.

Nope.
This kind of thing does not belong in the DNS. If you want to do
load balancing, you should do it with mechanisms that do not involve
the DNS.
At the first level, you can put a Layer Four (L4) load-balancing
switch in front of the servers to be balanced, and the switch will
use any of several different methods (none of which depend on the
DNS) to determine which server is the "least loaded" and therefore
should be the one to handle a particular incoming connection.
See the archives of the load-balancing mailing list at
<http://www.vegan.net/lb/> for more information.
