Licence question

[Company Man]

Suppose a commercial company is building a new appliance or tool of some
type, packaged in a sealed black box.  This hypothetical company would
like for the appliance to have a standard Python interpretter embedded
in it.  The users of the appliance, customers of the company, could send
Python instructions to the appliance via a data link.  Those
instructions might be function definitions to be stored on the appliance
for execution later, or they might be simple commands to be executed
right away and then discarded.

What obligations would this place on the company that sells the
appliance?
