I've just read the Sooloos licence agreement (ControlPC -> Settings -> License) and I believe you CAN copy/clone the software.
You may not use or copy the Software ... except as expressly provided in this Agreement.
Or put another way: If you adhere to the express provisions provided in the Agreement, you
can use or copy the software.
What are the express provisions? I'm glad you asked

Meridian hereby grants you a limited, non-exclusive, personal license to use the Software in machine-readable form only for your own personal use on the device on which it is pre-loaded for the sole purpose of operating and managing your Meridian Product(s)
My reading of this is that you can copy the software as long as the copy is used in the manner described above. i.e. you must put the cloned/repaired disk back in the Sooloos device.
I'm curious what the legal powerhouses that rule the board think of this interpretation?
BTW IANAL
