ICP Emulation

An older blog post on the Varnish site says this:

"... you can emulate ICP-like behaviour by writing VCL code to check your
neighouring cache for the request that you are looking for. Setups like
these have been discussed on
times and implementing it should be fairly simple."

I must be searching the wrong terms, because I can't find any descriptions
of this.

It looks to me like the setup would be little more than setting the peer as
a backend and then setting req.hash_ignore_busy on one of the servers to
avoid race conditions, as described on the wiki. Is there anything I'm
missing, or does someone have a reference on how to set this up? Any help
is appreciated.
