AS macros, when used, will handle new ASes just fine.

It's an option which potentially scales nicely.  We'd coordinate this on
a per peer basis rather than on nanog though.  :-)

I haven't counted recently.

I'm not parsing this one.

Two possible ways:

1) in the future setup with AS macros, it would be treated consistently
   wrt. the macro in which it sits, assuming that we already have policy
   for that macro.

2) in the current setup, one of our tools picks this new AS up and we
   write policy in our aut-num for it.  If it's not obvious, we
   coordinate with appropriate peers.

Not likely today.  Future (i.e., with macros), sure.

We have a few AS macros ourselves.  For example, AS-ANS is our top
level.  I'll admit that if these are to be used correctly, they
have to be maintained (that's a pretty easy task really, unless
one is trying to clean up lots of other gorp first, which is the
current case).
