I missed this meeting/preso when it happened (yes, 5+ meetings ago)

<http://www.nanog.org/meetings/nanog45/abstracts.php?pt=MTE4OCZuYW5vZzQ1&nm=nanog45>

I note the talks about using spoofed source packets to do some
measurement, I didn't see anyone in the video say: "But spoofing is
bad, but you want YOU to be able to do this? what? isn't that a little
hypocritical?"

Isn't it? and why would someone (an isp) disable BCP38 for this sort
of activity?
