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.
