It appears that the FAA considers attachment mechanisms such as
Velcro, clamps, duct tape, bubble gum, etc. to be temporary and
therefore acceptable for a non-certified individual to use to
temporarily install equipment. I think one key is the TEMPORARY
nature of the attachment, it is expected that the installing pilot
will remove it before some other pilot flies the plane, thereby
returning the aircraft to the condition described in the airplane
flight manual.
