It looks like Apple might just be live streaming today's Back to the Mac event, though the announcement so far is lurking only in the darkest backwaters of media alert-land (i.e. RSS aggregators):
What: Live video stream of Apple’s October 20 event
When: Wednesday, October 20, 2010, 10:00 a.m. PDT
Live Video Streaming
Apple® will broadcast its October 20 event online using Apple’s industry-leading HTTP Live Streaming, which is based on open standards. Viewing requires either a Mac® running Safari® on Mac OS® X version 10.6 Snow Leopard®, an iPhone® or iPod touch® running iOS 3.0 or higher, or an iPad™.

Hopefully the media alert is legit and starts propagating soon. If so, tune one browser window to Apple.com and the other to TiPb's live meta blog, and let's watch together, shall we?
