	Yeah, and it was obvious to me, it just seemed like Paul was making a

	Or, ping something you're explicitly allowed to - that encompasses
	"Ping something you own", which doesn't cover the explicit exchange
	of favors between two parties already trading services (say, secondary
	DNS hosting), but is still a very valid way of doing things.
