[AG-TECH] AG on wireless

[Tony Rimovsky]

But in practical application *today* on the AG, windows media
compression is not in use outside of your lab, correct?  Will there be
a way to use this compression from a linux based video or audio
source?  I'm not trying to stoke OS flames here, just curious.  I
haven't looked into licensing/source/etc for this at all.
