Exactly one. Same as in IPv4.
=> I think this interface will be selected according to the routing table,
ie. in general it will be the interface used for the default route, won't it?
(it is what happens with IPv4 and sin6_scope_id (in your proposal) will
not be used for the outgoing interface selection itself, only for a check
about the selection soundness, ie. with only a little improvement over
standard IPv4 multicast for emission)

PS: about the (still missing) scope/zone specs, the zone A `is included
in the zone B if A < B (using for A and B the multicast scope numbers
like 2 (link), 5 (site), 8 (org), ...). This is in *no* current specs...
