You should be able to do this with TDMoE (TDM over Ethernet) which is
a little-used feature of the Zap drivers. There are two ways of
doing this: individual trunk groups in a cascading failover
situation, which is a well-known configuration with TDMoE (see below
for howto) and then perhaps a more interesting way that creates one
huge trunk group spanning multiple hosts, which is not documented in
the howto but I can't think of why it wouldn't work.
I have not actually tried this, but in theory it should work as long
as your servers are all on the same ethernet.
See Wasim's mini How-to on http://www.convergence.com.pk/TDMoE-HOWTO
and then think about it for a while and modify it so that the group
spans multiple hosts. Let us know how it goes; I think this might
actually be a pretty interesting experiment if it functions as
