Load balancing w/ failover.

Hello, I would like to know the easiest way to setup the following:

4 DNS servers running BIND 8
1 controller machine that distributes queries to the 4 DNS servers
evenly.
Controller will skip any machine that is not responding.
None of the DNS server are authoritive.
I would also like a way of sharing cache, or sending like queries to
the same box since the domain record would already be in cache.

I need this setup for my Lyris ListManager box, it is killing my
current DNS server. Lyris says not to just setup multiple DNS servers
as if one fails, it will actually slow down mail delivery more than
just using a single DNS server would. I would like a nice automatic
solution that always works, our lyris box cannot slow down :-). I
took a look at:

lbnamed
http://www.stanford.edu/~riepel/lbnamed/

And it seems to lack good docs (maybe I have not dug into it enough
yet).

Does anyone have experience w/ it? Will it do what I want? Is there a
better/easier way?

Thanks in advance.
