[Standards-JIG] XEP-191 queries

[Mridul]

Hi,

  Just a couple of queries regarding 191.

How is the spec supposed to interact with the most available resource 
concept ?
I know that this is a concept I keep banging my head against :-)
The idea is something like , same node (userA) two resources (resP1 , 
resP2) with different priorities (both +ve) - higher priority resource 
blocks userB.
userB sends a message to bare jid of userA - what is expected to be the 
behaviour ?
That is , should server find out the most available resource from point 
of view of userB ?

How can a user block something like 'all except in my contact list' , etc ?
Should we fall back on privacy list for supporting this ?
I guess for selectively blocking presence , iq , message we MUST use 
privacy list ?

What happens when the user blocks his own jid ?

Regards,
Mridul
