If you try to access the Showtime US site from outside the U.S.A. it gives you this lockout message:
We at Showtime Online express our apologies; however, these pages are intended for access only from within the United States(Thanks Steven)
If you go through Anonymization, you get through. (Merci Karl)
Only to see that Showtime's tagline is "NO LIMITS".
Ya can't make this kinda crap up.
