Section A.1 of the impact analysis might seem counter-intuitive to some,
especially given the title of this policy proposal. Section 2.0 of
RIPE-525 (the current policy) states: 

    "In order to help decrease global routing complexity, a new AS
    Number should be used only if a new external routing policy is
    required, see RFC1930."

RFC1930 in turn lists some cases where an AS assigment is not needed,
especially in context of single-homing. Marco, am I correct in assuming
this reasoning has been followed? 

Section C:

Regarding "Potential Future Multihoming", why does the RIPE NCC need "a
time period allowed for multihoming"? 

Regarding validation of multi-homing: given the nature of BGP it is
extremely hard to assess whether somebody is multi-homed or not. I would
not expect the RIPE NCC to validate if somebody is multihomed, Relying
on possibly forged "show bgp sum"'s runs counter to the spirit of the
proposal: truth & accuracy are most important.

Kind regards,
