CJ sent out this note today:

AB 2078 has been introduced; this bill is similar to the Colorado bill which passed earlier this year. It imposes obligations on out-of-state retailers, but does not do so on the basis of those retailers participating in affiliate programs. However, Amazon expired its Colorado affiliates in response to the Colorado bill, so this may affect California affiliates. This bill is currently in committee and is scheduled for a hearing on 4/19/2010.
I don't see anything about this, any word on the hearing?
