*> I'll steal this topic as a chance for some blatant self-promotion:
*> Resilient Overlay Networks: http://nms.lcs.mit.edu/ron/
*> Take a small collection of hosts around the 'Net. They
*> can see different paths in and out of various ASs. Have them
*> measure the paths between each other, and if they can establish
*> a better route by sending their packets indirectly through another
*> member of the overlay, do so.
*> It's a rough approximation of the ideal that you're alluding to
*> in your message, since it has the obvious downsides of needing to
*> go all the way to the edge and then back in, and it's limited in its
*> view of the available paths, but it's one way to start doing some
*> of the things you're looking at. Works pretty well, too, especially
*> in the face of a few egregiously bad links.
Why isn't this the Tragedy of the Commons waiting to happen?
