I finally succeeded in getting Joost setup, they released a new beta and modified their servers. It is certainly a very pretty program but so far due to the beta nature of the system, I haven’t gotten to watch more than a few seconds of a program. I suspect the problem is adjusting their servers to handle the higher load from increased beta testers.
They have stopped accepting applications for the limited beta program but, they have promised that everyone who previously applied will get their invitation to join in the next weeks. They also appear to have stopped issuing invitation credits to current beta users (I get none). They expect to move to open beta testing for all people soon.
Once I get to watch some whole programs and play around with the features I’ll post a review.
