And aside from the other thread that spun off from this about the technological
pro's and con's around mcast, perhaps there's another line of thinking to 

Having seperate VLANs or otherwise "planes" may help a great deal 
operationally, by being able to introduce a ucastv4, mcastv4, ucastv6, 
mcastv6, etc etc.. place. (as long as you can keep the overhead down of 
actually running the "planes" themselves).  Has anyone gone thru the exercise
of worrying about such a thing/beast?


(and before anyone flames me for not saying it, imho, the point about jumbo
 frames is moot. no flame intended.)
