Delivering multicast to end users is fundamentally not hard. The biggest issue seems to be with residential CPE (pretty much the same problem as IPv6, really).
Well, more than that, since I don't really want my DSL pipe saturated with TV that I'm not watching, you need some way for the CPE to tell the ISP "send me stream N"
I suppose with some sort of spanning three thing it'd even be posssible to do that at multuple levels, so the streams are only fed to people who have clients for it.

Or your set top box... multicast joins from STB to DSLAM aren't so hard. AT&T U-Verse has been doing it for more than five years now. jy
