It will never become a paid product, it would require licences from both Crowbar Collective and Valve Corporation, too much money would be pumped for licenses even IF we got the permissions, it would never return profits.

As for free release, maybe. The mod is still being developed. If the process would be easy then why not.

I think you should do it because 1the install would be easy and 2WHY NOT

also even though it is now on the steam populer sectian it will still be more acsessable
