Well, all of the On-the-i.com mp3 multicasts for one :)

And (with the envivio plug in) the On-the-I.tv MPEG-4 streams as
well. (I am not sure that we have tested the DIVX stream with RealOne yet.)

We also have not tested the envivio plug in for WMP yet - it's not yet fully
released. AFAIK, this will be the 
first means of playing RTP streams with WMP.

We would love to add IPTV to our interop testing. You can send gear or code
anytime :)

Yes, this needs attention...
