I know that most of the JVs on this site are Internet Marketing related products and services.

I have seen the emergence of a few JVs in the "offline" space - dealing with people who want to do internet marketing types of activities as a service for traditional small business.

For anyone who has actually been an affilate JV partner to one of these product launches, how has it done in terms of conversion and sales?

For any product owner doing the launch, how has promoting your launch through JVs done?
