Distributing DNS servers

[Barrett Richardson]

I want to distribute my primary across a network topology for
various reasons. I intend to have an ip address for the primary
attached to a loopback interface on multiple machines at
multiple points in my network (and use OSPF or BGP to establish
reachability to various nameservers in various locations thru out
the network).

Issue 1

  With this scheme IP packets leaving the boxen must not
  have the IP address of the primary (which is on the loopback
  and not unique in the network) but the IP address of the
  ethernet (which is unique). The idea is to have answers
  to queries to go the box that sent the query.

  Doable?

Issue 2

   I have this fear that an undesirable side effect will result
   from the cacheing behaviour of remote servers that query my
   nameservers. For one, the reply is going to come from an IP
   for which it has no NS record for my domain, will this be
   a problem?
