route filtering policies (from "split b" thread)

i suggest that this has been discussed to death on the nanog mailing list,
and, like other internet discussions, is repeated every six to nine months.
there is little need to repeat the discussion here when you read the
archives over there.

my original question was merely whether arin had changed policy or whether
something else was going on.  it turned out that, despite ill-considered
comment to the contrary, arin has not changed policy, and the apparent
problem was either a bug or a communication issue between private parties.

we can all go back to sleep now, learn how to [un]subscribe to internet
mailing lists, and other exciting things.
