Yes, from what I have seen this is probably quite true.

I have seen low cost linksys CPEs running IPv6/PPP/L2TP. I can't imagine it is 
too difficult for others.

Certainly. Big enough perhaps that each can support their own tunneling protocol.

Given the different characteristics of the underlying network, variant platform 
geneology, as well as intended application, usage and necessary time-frame, I 
have wonder if there is a lot to be gained from trying to force a single 
one-size-fits-all protocol here.
