So Ustream keeps sending emails announcing they are broadcasting with no mention of the password or when it will be actually available. That is a great way to frustrate your prospective audience. Thumbs down - to the Ustream communication system. (Not to the poster here;^)

Putting it another way, what's the seekrit time the channel is open, or does the thing start the moment a few tens of thousands tune in at 8:00 Eastern? Can you say "load balancing" (by common sense methods, like half hour [virtual seating] lead time)?

Given the Atlas Ustream no-show a couple weeks ago, I'd also think about a few live tests, hours, tens of minutes, minutes before "showtime," calling for feedback (from the outside audience, i.e., viewers like me) on A/V quality. I don't know whether you're aware of this, but some Ustreams have soundcard-damaging audio levels, and yours is one of them. Furthermore, decent playback (let alone Webcasting) of a feature film is one seemingly simple thing theoretically, but quite another in practice.
