[Standards] Jingle initiate and resource determination

[juha.p.hartikainen at nokia.com]

Hi!

Seems that you are referring the well-known Forking as it is implemented
e.g. in SIP.

If the session establishment is based on resources at originating site,
then the forking
have to be implemented to originating client. Still currently XMPP
server knows certain 
bare jid's available resources and can fork the messages to all, like
e.g. IM  either 
Presence. 

Cheers,
<Juha>
