I am behind on email, but better late than never....

This part troubles me. This is a significant change from current policy 
on guaranteed routability, and also quite a deviation from the critical 
infrastructure policies of the other RIRs. I would like to remove the 
"likely not to be filtered" from the above, or add that at no times can 
the RIPE NCC guarantee routability or wide reachability and acceptance 
of the assigned prefixes.

I don't see why RIPE need to assign a /32 when the other regions are 
/48s? I would also like to add that these assignments should be made 
out of a single block.

Also, to follow the "have you considered private address space" (or 
whatever the exact formulation is ) question in the PI application, I 
would like to require the applicant to consider using an existing 
anycasting service. YEs, I understand that that is a business decision, 
but so is accepting these prefixes by the rest of the world.
