Guys,

	This maybe totally stupid, but what about a walking
	ping when dealing with "a subset". Only the ping reciepents
	respond if the TLL is decremented to 0, or the equiv.

	Or only the respondents within the walking radius
	responds..

	So, it would be something like:

		ping walk 5 : where 5 is the radius of the ping

	This way you can build a explicit source route, if
	the ping reciepents are somewhat stable, and/or...

	And gives you a different subset of responders.
