+1 to Chas: " The POD Farm licenses are hard coded into your GX, and cannot be used by any other devices,  The only licenses that are transferrable are purchased licenses, not the ones that come free with hardware."

http://line6.com/community/docs/DOC-2277 spells it out like this:

Can I remove licenses from my Line 6 device or transfer them to a different Line 6 device?
Since your purchased licenses are attached to your account, and not your devices, using licenses on different Line 6 devices is only a matter of authorizing the devices.

NOTE: One exception is “Factory Add-Ons”. These are features that can only be used with the device it came with and cannot be removed from that device to be “shared” with your other Line 6 devices. For example, POD XT Live comes with an FX Junkie Add-On. After authorization, License Manager does not make that unit’s FX Junkie available to your other authorized devices.
