Only thing is...is there any way you can share your TV with guests with orb? I find the only way to view TV content from orb is to log into your own account. Youc an't share out the stream unless you give them your account info.
If you log on to your ORB account online, you will see a link (with a picture of a folder IIRC) that says "Share Folder". You click that and it asks you to set a a group with email addressses. It then sends an email with the link to your orb with a guest pass to watch your videos. So yes, you can share it with out giving out your info.
