[squid-users] accel mode and peering

I am fairly new to squid and have what may be a couple newbie questions. I
am attempting to set up multiple squid caches in HTTP accelerator mode to
cache a pool of HTTP servers. The way I was thinking of setting them up is
to load balance the squids in addition to the real HTTP servers (using an
existing hardware LB device). The content I'd like to cache can be rather
large (large files are 1MB+, other smaller content exists as well). Each
server has ~50GB of disk for the cache, with at least 4 squid servers. The
total amount of content on the real servers will be 500GB+, via NAS, and I
want to try to reduce the NAS traffic.

I'd like to maximize the amount of frequently accessed data that is cached,
so I was debating using peering to split that content across the pool of
cache servers. I've tried configuring ICP peering (unicast) with each
server as a sibling to the others, and digest are enabled. I don't know if
this is the best config, but even still, no ICP traffic is occuring. This
is what Cache Manager has to say about it:

icp.pkts_sent = 0
icp.pkts_recv = 0

Per-peer statistics:

peer digest from 10.1.8.112
no guess stats for 10.1.8.112 available

peer digest state:
        needed: no, usable: no, requested: no

So, here are my questions:

Am I missing something with the cache peering?
Is unicast ICP the preferred method to reach my goal?

Thanks in advance,
