Earlier quoted context omitted.
The lack of a true, independent, freestanding multimedia application which can handle this sort of thing -- building and managing queues, interrupting, deleting, sorting, etc. -- puzzles me. The browser is such an obviously poor place to stick A/V. Other than, of course, the fact that advertisers slobber over cramming every more crap down some "channel" or other.
Well, Google has a history of preferring HTML above all other interfaces. Only when someone else comes along and offers a better native interface, they jump in. Thank god there's a native iOS/Android client.
Meredith L. Patterson has addressed the point of Port 80 (or 443) adequately. For the time being, we're locked into that.
My point is that handing of A/V material to a dedicated AV app is, all else considered, probably optimal. It's the 4th browser replacement mentioned in my "Tabbed Browsing" rant, elsewhere in this thread.
