Can't find ipayment module

The very first payment option listed on http://www.zen-cart.com/content.php?14-Payment-Processing is "PayMeSecure/ipayment".

But, when I go to payment modules I don't see it listed there. I tried googling it thinking it was an add-on module, but I can't find it.

Is this no longer supported?

It may be you need to sign up for the service to have access to the module.

Which service on the linked page are you looking for?

I am also confused. On that page it reads "PayMeSecure ... 100% Online Application ... Fully Integrated With Zen Cart, but I don't see a payment module nor plugin.

It get setup through the authorize.net module neither right?

I also do not see if it takes a customer off-site like paypal express, or if they stay 100% on size (no frames nor nothing like what paypal advanced is described like).
