My problem with HBO GO is that it apparently requires you to have a cable subscription that includes HBO. Fortunately they finally came to their senses and now offer HBO "Now", which is a separate, online-only, offering that doesn't require cable. I wouldn't be surprised if Now is still geo-blocked though.
