There really is no reason that everyone has to be behind a LSN.
ISP's offer residential customers differentent levels of service
today.  See the web pages to re-open port 25 for examples of this.
There is no reason that they can't do a similar thing to move
customers who are doing things that break with LSN out from behind
the LSN.

Also when Microsoft and Apple have shipped fixed versions of IE and
Safari that have sub-second failover most of the visible issues
with broken 6to4 tunnels will disappear.
