openbsd igmp v3 proxy?

[Tobias Wigand]

hi,

lately my ip-tv provider switched from igmp v2 to v3 and my openbsd 
setup with igmp-proxy from ports stopped working. if i get the v3 rfc 
correctly, it4s not conform to the igmp standard to cut support for 
older igmp versions but they did it anyway.
i found 
http://potiron.loria.fr/projects/madynes/internals/perso/lahmadi/igmpv3proxy
but it won4t compile. i browsed through openbsd4s source and noticed, 
that it only seems to support igmp v1 and v2. the kame patches for igmp 
v3 seem very old (openbsd 3.5.) and i don4t think they would apply to 
openbsd 4.4.
so my question is: even if i did have an igmp v3 proxy for openbsd, 
would it help me at all as the os does not seem to support v3? does 
anyeone have a working igmp v3 / multicast setup and can point me to the 
right directions or just shed some light into this?

cheers
