It seems that the folks that run Skyfire have taken it down. Read this:
http://www.skyfire.com/press/blog/68-skyfi...-hours-sold-outGuess that the app was so popular and since it requires Skyfire servers to change a flash video to HTML 5, the system got bogged down. According to Skyfire they are sold out because of not having enough capability to transer all of the requests.
Maybe this process is not good if it requires a quick response, it's almost like the little boy putting his finger in the dike to hold the dam together and they it busts.
Feel that this Skyfire system will fail because they won't be able to handle the workload
Wait til they get more capacity.
