There is a DASH Industry Forum with members like Ericsson, Harmonic,
Microsoft, Netflix, VisualOn and many others.


Since the DASH standard is so wide and open (there's no good reason you

* develop test media (which usually is not licensed for distribution outside the group)

The members of this group are mostly companies who sell client and
server software and hardware.  Some of the individual people have the

There are companies working to deploy DASH (Netflix is already using
