I think Mr. Simpson was referring to the outbound traffic in this case, not FULL transit. Of course you have to manage a way for that traffic's return packets to find you. In a lot of ISPs cases, the outbound traffic is a 3:1 ratio. So if you can dump your outbound traffic onto an unknowing IXP member, your probably in luck. Then just simply order an SMDS connection to CIX for the return path at ever-so-fast lightspeed.

Worse, the current technology used at the exchange points could encourage abuse. What is to stop anyone connected to an exchange from simply dumping packets anonymously at the link level into the various inter-exchange providers' routers and getting free transit?
Typically peers configure their routers so as to keep routes learned via a peer internal, and not advertised to other peers. Therefore, you _can_ dump all of your traffic to one of your peers, but your traffic will not come back to you via that same peer, because they are not announcing your routes to anyone else. Real transit _requires_ that the transit provider advertise your routes to other providers. Nothing less will work.
