ISP == "Internet Service Provider".  The key word here is "service". 
tiedyenetworks.com is a provider of services to customers, and I suspect 
those are retail customers.  What he just told you is that the service 
he provides, in his experience, does not play well with IPv6 AS 
CURRENTLY IMPLEMENTED IN AVAILABLE EQUIPMENT.  On the one hand, IPv6 is 
"the future" (I just invested a fair amount of cred to get the books 
recommended to me here on NANOG to get up to speed) but like early 
versions of just about every thing and every product, there are still a 
few potholes.

tiedyenetworks.com, from my reading of this thread, has elected to limit 
his service offerings to his customers that he can reasonably support. 
That's good, solid business sense.  Nothing is worse than providing a 
product that does not work as expected or advertised.  VW, anyone?

And unless there is a damn good need for that multicast traffic, it gets 
blocked.  From my edge network, I block multicasts and broadcasts both 
inbound and outbound.  When I was network admin for the web hosting 
company I worked for, I also blocked a number of ports at my edge, ports 
that had no business being used in the general case.  I had *one* 
customer that needed to come in using 3309; I punched a hole in the ACLs 
for that one customer, and damn carefully.

Maybe you missed his earlier declaration:  "I'm a provider, not a 
developer."  He expects the equipment to work.  It doesn't.  Did he ask 
his vendor?  I don't know, but my personal experience with 
wireless-equipment vendors is not encouraging.  Some people don't have 
the money, resources, or time to winkle out all the wrinkles, so they go 
with what works in their situation.  Consider the rural market:  damn 
few customers, so $150K engineers are out of the question.

That's your experience.  He has a different experience.  I suspect your 
customer base is considerably more dense than tiedyenetwork.com's base. 
 Did you say you are primarily a rural provider?  Mike did.  Your 
earlier traffic suggests your base of operations is more in a city or 
suburban environment.  Apples and oranges, if true.
