For an example of BEEP peer chains and tunnelled security, see the TUNNEL
(http://www.ietf.org/internet-drafts/draft-ietf-idwg-beep-idxp-02.txt) we
use the TUNNEL profile to provision a chain of peers, then tune with the
desired security profile (most likely TLS) before binding the endpoints to
the IDXP profile.
