	15 years into the exchange trade has given me the following insights:

	RFC1918 space can be used - but virtually everyone who starts there
	migrates to globally unique space.

	Private ASNs - same deal.  Private ASNs tend to have special treatment
	inside ISPs - so path matching gets you in the end.
