The Albert Hall thing was a one-off event staged for schoolkids. Schools could enter a competition to win the chance to buy tickets. Om's class were really lucky and were right at the front - Om's face appears several times on the webcast.
It was transmitted live initially - then its left on as an archive for the next week - so you can connect in and listen anytime.
On a 56k modem its not great quality - just slow-changing stills from the video stream + reasonable audio.
I watched it live on the broadband link & that was fantastic.
Its very good - the interview bit is quite interesting, but her reading is absolutely stunning.
