After a lot of pissing and moaning, A+P was finally published as RFC 6346. It only took five years from when I first presented it.
All due to the hard work of Gabor Bajko, Mohamed Boucadair, Steven M. Bellovin, Luca Cittadini, Olaf Maennel, Reinaldo Penno, Teemu Savolainen, and especially Jan Zorz.
