Christian,
It sounds like you are doing great work out there in California - Neverware is happy just to be a part of it.
When working with computers which you plan to provide for individual use, there is no need to pay for CloudReady. The
free version is available to anyone for any use.
The only things missing from the free version are official support and access to Google's Management console for
central management of the computers - which it sounds like you don't need.
So you are more than welcome, even encouraged, to use the free version of CloudReady as widely as you like. We're happy to have it be a tool your organization uses to do some good.
Best,
