Is this just a relict from the past or is this a showstopper for me? (I use an Debian-based system)

I'm running Arch and received the same message. Ran the test video and it seems fine to me. Likely what they're saying is that they don't promise compatibility with Linux.

The webcast is something of a flashtastrophe:

  * Chrome is not officially supported
  * Need to allow pop-ups
  * Chat widget does not do copy & paste
  * Chat widget takes 10 seconds to scroll
  * Shockwave Flash process using 350% of CPU
  * Webcast crashed and had to be restarted from the broadcasting-side
  * Chrome repeatedly asking if I want to kill unresponsive webcast tabs

That said, they have a decently slick UI for handling screen sharing, slides & chat. It's just that the implementation is a nightmare.

O'Reilly & on24 need to rethink this.

Do you have to watch it live or well there be a download / stream we can watch at our leisure?

Yes, it will be recorded. Of course, that won't help you troll me in Q&A, etc. ;-)

Thank you for getting it recorded.

Sad I missed this, but was wondering when / where the recording will be posted?

FYI, I have published an equivalent video here:

What are the pre-requisites for this webcast? Setup etc? Thanks for sharing :)

Found it quite nice - the time was limited of course (and with some difficulties even more reduced), but I love to peek over peoples shoulders. And I respect the guts of doing this live in the first place.

Ha! I use it all the time. Just the other day someone asked what this mixed windowing system was - I just explained and they say Doh!

Darn - commented in the wrong place - now I say Doh.
