Thanks Badru for posing these questions.  I offer some answers that  
are my personal opinion only, meant as a straw man. I am no expert and  
participate for discussion purposes and learning.

I think that the answer has to be yes. Is it possible for it to be no?

I don't think that they necessarily need to be uniform policies but  
there must be - and already are - such policies, I believe.

No, I think this should be handled by each RIR.

No, at this stage I think we consider some cases.

This needs to be phrased in plain english but I attempt a response.

I think that there will be a "deleterious effect" if some RIRs are  
dictated to by other RIRs. This will basically make things very  
difficult as members lose control of their own policy making roles and  
responsibilities.  So it will be far better to allow each RIR their  
own policy, although in my experience there is a sufficient cross  
pollination of policy makers to ensure that they are all aligned.

I think not until we know more.
How is this different from Qu1?
