source filtering

	I'm interested in what providers actually do source
filtering of their customers.

	Including:

	1) Using access-lists to filter your customers
	2) Using the "ip verifiy unicast reverse-path" Cisco feature
(it's in 11.1CC images when you use CEF, so I don't get a flood
of e-mails)
	3) Using other router vendors and features you have to
filter source addresses.

	I'd like to summarize this all and start a quest to fix
providers that don't source filter (as people quest against spam, and
against smurfable network blocks).
