Scott,
World Possible has recently deployed our RACHEL-Plus server with the NY Dept. of Corrections in several of their facilities with juvenile inmates. Our RACHEL-Plus server includes the latest release of KA-Lite server and content on Ubuntu Server 14.04 version of the Linux Operating System.
With the partnership we have developed with the NYDoC we might be able to help you get servers approved where you are teaching. We can offer this same assistance in quite a few other states.
This is a link to our US Justice program. You can also email me at ed[at]worldpossible.org .
Best, regards, Ed Resor
