[Bloat] Re-ECN

[Dave Täht]

JG's blog comments contain a wealth of information as yet unexplored and
quantified. I ran across mention of re-ECN[1], which seems to have some
potential. 

In particular, I liked the full backward compatibility with RFC3514[2].

Is the "is it safe to use ECN" research going on exploring what happens
when the last unused bit in the TCP header is also set?
