No it is not. I have no reliable access to mbone and multicast penetration 
on public Internet here in central europe is "not very wide". So it makes no 
sense to deal with multicast. Rather I'm investing my time to support IPv6, 
this looks like it has more perspective :-)

> what server software you use for ipv6 streaming  ?

Windows Media Server on top of POS (Picture Operating System - WM 2003 
server).

> is there a way to stream via rtp/ rtsp over ipv6 aswell ;) ?

WM is serving data over rtsp as well as over http. ASX file is only pointer 
to the stream. As I understand the technology, server will negotiate with 
your client and they try to use ports in following order 1775 (mms) -> 554 
(rtsp) -> 80 (http).
