	Scale has become my favorite term from vendors that sets off
alarm bells.

	The problem is usually limited by someones imagination like
"why would you have more than 1 comment/remark", or "what do you mean
a customer has 200k prefixes registered".

	it all depends on who/where and what role you play.

	We have tried prefix filtering peers before.  It's an
excercise in frustration when it comes to vendors ability to
ingest the large sets and/or changes.  I talked about this
privately and at things like IEPG.

	The situation and technology haven't substantively changed
in the interim.
