Publishing a new application to marketplace issue

[developer....@gmail.com]

Hi guys, I’m new with the marketplace and I’m developing an application to replace google's login with my app, which uses strong authentication. 

To use it you don’t need to install anything, it’s only a matter of configuration of your google app. When you try to access mail.google.com/a/yourdomain.com it will redirect to our application where the validation process occurs, and after validating it will return to google web site.

Same happens with logout and password change, you will be redirected to my app.

When a user needs to change the account password, we use google admin api to change it, of course, it requieres a previous authorization from a domain user with administration privileges.

Question is, how to publish an application like this on the market place?, I don’t see how to do it according to the new regulations from november 19th, for example, the application type and the fact that it should be an installable listing.

Someone who can give me a hint or example.

Thanks in advance.

Fernando.
