Ok, fair enough.  But to keep the simplicity of the solution I
described (<video> plus JavaScript include), we'll need it hosted on
some central FQDN that designers (through mv_embed) can refer to.  So
we will need the Cortado applet to be CA-signed.

20% of 60% still gives us 12% of all Internet users that can't play
Theora.  That's pretty big and not very competitive with Flash
deployment.  This is the main reason I'm hoping to get the VLC ActiveX
control in better shape.

Yes, that's what I'm hoping.  With CA signing, we can make the process
at least appear safe, even if the user still needs to click "Install".
