A sufficiently skilled flash developer could get the theora decoder
running in the flash VM using tools like alchemy (or a rewrite). No
one has done this yet.

Firefox will not be the only browser.

The most recent Chrome builds support Ogg/Theora and Opera will do so.

Safari also does if you install the XiphQT plug-in set.

Keep in mind that flash in the default OS installs is a fairly recent
thing, the whole world got flash by installing it.

You can play in IE using Java (cortado), as well as the VLC activeX
plugin.  By using Javascript on your page you can auto-detect which
methods are available and fall back to whichever will work best.

Here is a simple page that falls back to Java if the video tag is not
available: http://www.celt-codec.org/presentations/
