Now, in your example, if OB_1 and REG_2 fail you don't still don't have
redundancy :)

I don't have the spec in front of me, but I don't think it currently
talks about multiple contacts.

I guess this all comes back to Dean's question whether we need some new
text into the draft.

In order to avoid delaying the Outbound spec even more, I guess it could
also be an extension draft:"Outbound with multiple contacts", or
something like that...
