You can find much of the background export control information on 
Bert-Jaap Koop's Crypto Law Survey:
http://www.cryptolaw.org/index.html

Also good information on the various lawsuits challenging export control 
over the years.

One of the reasons for relaxing the export regs was that they were 
hurting US businesses.
The regs made creating crypto products much more complex as you needed 
to have different versions for different export regimes.
