Off topic, but your post tweaked my brain's processing. I read those not as bullet points, but as a boolean search.

"It needs to be an Apple device, but not iOS, not Safari on OSX, and not an Apple TV."

I was trying to figure out what Apple Devices were left for a second before it clicked ;)

In the past I've been able to get around this requirement by getting the stream directly. If today's anything like previous events, should be able to use these URLs to open in VLC (the URLs will change when the stream goes live):

If you are using Chrome press F12 to open the devtools. Then press Esc and to to the "Emulation" tab. now choose an iPad or something and spoof your user agent as that.

it's dumb, but i think that should work. You will need to have QuickTime installed though, I don't think there's a way around that.

Apple fan here, but this doesn't make sense at all. Foolish and arrogant.

Or there are some live talkings http://www.ustream.tv/leolaporte

Is there a stream for Linux users? (without vm)

I'm certain there will be people on UStream and livestream doing mirrors.

Yes, this upsets me a bit. I like to watch live product announcements.

Apple does user agent sniffing? Is Safari becoming the next IE?
