Hi AJ,
I think that now CloudZoo being a production-ready licensing approach for a released version you should consider being logged in into your rhino account as a way to validate access to downloading installers, if your login gives you access to license usage.
Problem:
Right now if I go to find the installer for Rhino WIP I encounter this:
That requires me to know the email and license key used. This is a bit of a hassle but of for my personal case. But anyone in my team of licenses will be prevented from downloading a version because they do not have this information. Another approach is that you let them in, if they go to the downloads page from their logged in page in Rhino3d/licenses.
Thanks,
Gustavo
