I'm developing a wordpressplugin that will come in 3 sizes (with 3 licence types).

Ideally I want:

> Customer to purchase via JVzoo.
> Customer to receive email with login details to their member area.
> Customer to login and see the plugin available to download and their unique licence key.

How is this best achieved? (I'm putting the product on JVzoo if that makes a difference).

Thanks.

Richard
