         Encryption is a wide open concept. Are we talking password
protection, Digital Rights Management (DRM) Features, what?

         US export restrictions were lifted in January of 2000, HOWEVER
there are some countries that still do maintain restrictions PLUS there are
issues with export into the 7 "bad guy" nations.

         This is NO LONGER the case! You are working from old information.

         Before you go off and do this, there are MANY other things to
discuss (IMHO). Why are we encrypting the data? Where do keys (if any)
get stored? What algorithm(s) should we be using, and why? What DRM
support (if any) should we be looking it?

         Let's not just do a "quick and dirty hack" here. If we think this
feature is important, let's figure out what the feature really is and the
right way to implement it.
