Correct me if I'm wrong but the problem I have with script you linked is that it relies on the WebUI provided by the tablet.
This WebUI does not work unless the USB interface is connected or you give it an IP after each reboot [1]. I wish there were a simple way to push and retrieve files from the tablet without relying on too many hacks or too much patching that would reveal maintenance heavy over time. There is one script that might be the one but I haven't tested it yet [2].
