multiple backend + apache bottleneck

Hello all ,

We are using zope/nuxeo cps  with 8 zeo clients and I test varnish 1.3 
in place of squid 2.6.
squid uses 8 zeo peers and if I've understood well varnish can  have 
"only one" host per backend.
is there is a way to load balance upon multiples hosts with varnish ?

Varnish is so fast that the bottleneck is now apache ( we are using 
apache with  MPM workers + mod_rewrite in front of our site ).
Performances are equals  in that design with squid / varnish ( near 1000 
r/s on a quadriprocessor)
Not really a varnish question but maybe you can give me an advice to 
have a full  profit of varnish.
