The TurboFloat Server design requires admin access because Linux APIs do not provide enough access to fairly basic things.
They can run on Windows without "root" access. Or, coming soon we're offering a hosted version of the TurboFloat Server that runs on our infrastructure.
Or, if they're set on using Linux, and set on using it on devices they control, they can always buy a low-cost device like a raspberry pi (or one of the thousand alternatives) and put the TurboFloat Server on that (we have an ARM version of all of our products).
