Just a quick review of the site - the "Product" page - shows a lite version and a pro. Lite has debugging symbols built in that can't be stripped. It is compiled at a lower optimization level than pro.
It says for Access to Source: Lite - Limited, Pro - Unlimited
Not sure what that means though, I didn't dig very far.
Found the above here: http://www.minocacorp.com/product/ - scroll down a bit to find the product comparison. I quickly checked each top level page and did not see any prices. Unless I missed something it looks like it's a contact us and we'll tell you situation wrt pricing...
All software licenses are limited. Im limited to following the BSD license conditions in BSD licensed software or I won't be able to redistribute the software.
The only non-limited license is the non-license that goes under the name public domain, but then I am again limited to only use software that was developed 100 years after the developers death. Some punched cards "programs" from IBM in the late 1800s should thus now be the first unlimited "software" which everyone is free to use.
Yeah, the site seems to get right to the point on how to download and install it so I can see why the OP started with that link. As mentioned above price and details on what actually is different between the two versions is a bit lite on details but seeing the OP's comment below mine suggests they are working on it...
Looks like an interesting project though. Going for Posix compatibility and having a working sh, gcc and python to start with can only help garner interest.
You could always put it under the AGPL 3 (or later). Your prospective customers would probably still want to buy a less restrictive license from you, because they are irrationally afraid of the GPL, especially GPL3, and even more especially the AGPL 3. But free software would still benefit from the source code being free.
