There are at least 2 (that I know of) affiliate setups that let affiliates in these states continue to get paid.
What they do is sign up as a sort of "sub-affiliate" under the main affiliate. The merchant is partnered with the main affiliate. (who lives in an affiliate friendly state).
The affiliate code is changed and the sub-affiliate is paid by the main affiliate (who takes a small cut of the commissions).
I have no idea what the long-term viability or legality of this is, but these kind of schemes will probably continue to pop up though.
