This could be done manually by hardcoding a timelimit at the top of script.py, using the time module.

import time
limit_str = 'Wed Feb 26 12:30:00 2014'
limit = time.mktime(time.strptime(limit_str))

if time.time() > limit:
    print 'Demo time expired!'
else:
    print 'Program logic here'

Hah, I suppose that's true! Getting the time from somewhere online sounds as good a solution as any. – Tetrinity Mar 04 '14 at 14:12
