	ARINs use of registry technology post-dates this split.
	One presumes that Mr. Bush pulled the relevent information
	from the ARIN routing registry via whois.

	Well, I beg to differ. A policy decision was made and the
	split was done. This may have been done as a "one-off" but
	it does provide a prior-use argument for future splits 
	to occur. I agree that existant ARIN policy (as I understand it)
	will allow such splits to occur. Perhaps ISPs would begin
	to realize that a blanket summarization of filtering is prone
	to many errors, esp. due to historical delegations and policy
	considerations that are now OBE but have been grandfathered in.
