Intechnic developed In-Portal has modules can be downloaded from http://www.in-portal.com/features-modules.html page. All but In-Commerce module are free for download. Apparently some time ago the In-Commerce module was also made free it's possible to download it without restrictions from the http://www.in-portal.com/modules/commercial-shopping-cart.html page.
Problem is that license check code in In-Portal itself still considers In-Commerce as paid module and requests a license for it.
