Purchase a Pretty Plugin or Theme + Affiliate Integration

Hi,

I like what Pretty Plugins does for the plugins page.

On the project page it states, "Combine with Pro Sites to create an awesome paid plugin store."

1. What does that mean? Does that mean, on Level 1 pretty plugins is activated, and Level 2 it is not? I don't get it.

2. Is it possible, to sell plugins individually so that a site owner can buy a little plugin for $6 (once off)

3. Can we combine this $6 transaction with the provider of the plugin so they get 50% cut? (I am thinking a Marketpress Chained Payment + Affiliate integration)

4. Can we do all this for themes as well?

Any +1's ?

Cheers,

Johnny
