Not that I can think of, and, the real problem with 6rd is that it doesn't matter what
size ISP you are... From the tiniest to the largest, they all consume the same
messed up prefix size for the same number of end bits to the end site.
So even a tiny ISP with 100 customers, if they want to give /56s to their end sites
will still consume 56-32 = /24.
