BigRedBox.tv is available...I'm still loving the branding...think of the youtube mock commercials you could post to your site...say it outloud:

Big Red Box dot teevee

...works for me...There is no mistaking the domain spelling and comprehension when saying it in your elevator speech when you guest at Rotary or other event.

The jury is still out for me on the dot mobi...I'd do a dot info or dot biz before mobi...no offense to Moby, who I really like...is he moby.mobi?
