Yep, I know routers will do it in the latest software, which I cannot 
quite run (needs a modest hardware upgrade), but I'm still playing 
around with the edge devices which is why I say "I think".

My routers will do SSM on IPv4 and IPv6, and they will also do SSM 
mapping, but I do need to check on the access pieces which prefer to be 
the customer's L3 termination (they CAN hand off L2 to another router, 
but my preferred routers are not designed for bulk BRAS use).  The 
access gear is somewhat in the "price point" realm and, while 
surprisingly capable, is not particularly well documented.  This was 
definitely on my checklist before committing to any multicast solution, 
especially IPv6-based, but I would like to hear your thoughts if you 
don't mind (via unicast or multicast as you deem appropriate).  I've not 
done a ton of IPv4 multicast and basically no IPv6 multicast in the 
past.  Many vendors are unfortunately just starting to catch up with 
mainstream IPv6 support in many cases...only took a decade (a frequent 
lament on here, I know), and multicast is still lagging in that 
department in many cases.
