Since Thusnelda (theora 1.1) that's only true anymore by fractions - and Theora
is still moving pretty fast. 

In a test I did myself, I got a (small size: 226x170) music video down to
64kbit/s with theora 1.1 - including audio (ogg vorbis). That's 2.5MiB for over
5 minutes of video. It's small enough to establish two-way video telephony over
an ISDN line (though when trying to use icecast for that, the lag is still too
high due to some buffers in intermediate programs).

(this video includes some evil optimizations, though - for example ripping out
almost all keyframes :) ).

The problem is that they are not *yet* enforeceable - many people in europe
fight to keep software patents illegal in Europe, but we don't know if who'll
win in the end. 

And for companies wanting to distribute software with some device, not having
that device distributable in the USA often is a showstopper. 

AFAIK H.264 will begin to take royalties from playback software in the next
years, so a program like Firefox can't include it without fear of having to rip
it out again later - and the same is true for distributions shipping KDE, so
H.264 shouldn't be a webstandard.

Cool! Many thanks! (moved to ~/bin/ :) )
