Regarding the SaaS as a service, it might not be precisely what you are thinking of, but im working on a SaaS-in-a-box sideproject that includes a lot of those things. You can find it here, all ideas are welcome!
Maybe I am blind, but I don't see a license file anywhere, could you point me to it. The closer thing I found to a license file was this (in composer.json):
"license": "MIT"
I'll take a look when I get home and add it if I forgot it! It shouldnt be much different than Laravel's own, since its basically just an extension of that. Thanks for pointing it out though Jorge!
