It's not trivial, and not just a matter of throwing in a few <video> tags.
 Television broadcast standards in large parts of the world (US, Canada,
Australia, etc) don't support codecs which are compatible with HTML5 video,
and then in the places where they support the right codecs (Most of the EU,
etc) the streams are way to gigantic to stream natively (and at that point
you might as well just play the ASX).

Thus, the only way to make this work properly is to perform on the fly
transcode, and the devs have decided that running ffmpeg at the command
line is not a proper solution for the future.  So, someone needs to
implement a separate daemon that uses the libav* API to perform on the fly
transcode in a format which the requesting browser can handle-- and
depending on the browser that might by H.264 at x resolution and y bitrate,
or WebM at z resolution and zz bitrate.

All told, a lot of work.  Not impossible, just not trivial. That said,
it'll happen.  It's just a matter of when/by whom.
