	which is their choice.  please show me the mandate for accepting
	routes/packets from any/everywhere?

	me, i'd want the option to "block as long as it
	is announced by AS 0 and the whois data points to RIAA as the

	or - allow any/all traffic from - regardless of the
	blocking on

	the mind boggles.
