dean,

that is not true.  i sincerely hoped that outbound would help me to
implement redundant proxy/registrar without a need to for load
balancers, database clusters, or forwarding of requests between
proxies simply by being able to assume that if i have two ob proxies,
each ua would register all contacts that it has via both of them.  

this is a VERY simple, easy to understand and implement requirement
compared to anything else this working group has ever produced.
