IPTV - so much confusion

IPTV seems to be raising it's head more and more.
Confusion reigns!!!!!!!

Telco view: Triple or quad play = way to raise ARPU and retention rate
TV industry view: just a broadcast medium

Customer view: VOD or broadcast TV perhaps even internet on tv

Does multicast fit in?
Does IPv6 fit in?
Answer to both of above = yes.

I think I need to put a huge summary somewhere.

Or perhaps point them to IPTV magazine and totaltele and vendors like erricsson and alcatel and microsoft.

My research work since 1998 could be a useful starting point!

And IPv6 and multicast integration with quicktime darwin streaming server = DSS and IPv6 enabled clients is also relevant.

I'd really like some stuff from thomson as well since they actually make set top boxes for iptv for many standards (microsoft, standards based .....) . Bits of thomson are near by to monash clayton.
