I got an email today from them echoing what Scott said above:
Hi,
We would like to just send a quick update to everyone who applied to be in the Dish beta program. We have received a lot of responses from the forum post and are still going through our approval process. We understand the wait can be frustrating but please bear with us as we process all the responses. If you have any questions at all please don't hesitate to send us an email.
Thank you,
The Beta Team
