Or, if you do it using the same script (set to listen to both URL:s,
and differentiating on which location was loaded to run either branch
of the script), you could abuse GM_setValue and GM_getValue to
establish an elaborate communication protocol between the two frames
and GM script environments, aided by a polling setTimeout loop to pass
and listen to values between the two branches.

*Very* awkward, but doable, in a proof-of-concept kind of way.
