Good question! [They write](http://www.nimbios.org/videos/livestream):
> NIMBioS offers free live streaming of many NIMBioS events. See box below for live stream events and link to log in. After you log in by entering your name, organization, and email address, you will be taken to the live stream, **which will be active only during the event**.
> The live stream will **not** be archived, but individual talks will be videotaped and available soon on the [NIMBioS YouTube channel](https://www.youtube.com/user/NIMBioS).
There are already some videos there. I'll try to persuade them to video as many talks as possible! Thanks!
