The opening ceremony is definitely available on iplayer - all nearly-four-hours of it. :) Most of that's introducing all the various countries, though.

And while beta-ing would be great, right now it's enough to know that there are people who would be interested in reading it. (I'm having enough fun with it that I don't care if I don't get loads of comments, but I'd prefer not to be greeted with silence, y'know?)
