Like the strong policy that prevented Pakistan Telecom from announcing  
Youtube's /24.

There are conventions and practices that most ISPs abide by most of  
the time, all essentially outside the realm of ARIN policies.

This isn't quite accurate (at least from the empirical evidence).   
What you appear to be attempting to do is to maintain the policy  
status quo in the face of a different source of supply of addresses.

It isn't clear to me that this is actually all that desirable,  
particularly since the main beneficiaries of the current policy (the  
large ISPs) aren't actually going to be helped that much -- their  
consumption rate is too high.
