Targetting new datachannel to particular end host

[jtj02]

Can createDataChannel() have an optional parameter, targetId, to request a new data channel to just one other participant in the call and not to all as is the current default? It would seem you can do this now by simply calling requestChannel on just one other participant but this would leave extra state on the master end as it attempts to finish connections with other end points that do not want (or know about) the connection.
