I, too, am in favor of moving to MSNP1[145], if for no other reason than to
silence the complaints about the lack of status (personal) messages.  However, I
would like to point out something that Stu occasionally reminds us of--MSN has
disabled old protocol versions only once, and this was when they moved to
requiring SSL for login.  This was when we moved from MSNP2 (or whatever it was)
to our current MSNP9 implementation's initial form.

MSN is currently still supporting MSNP9 as needed because the only existing
official MSN clients for Windows 9x are capable of nothing better than MSNP9, as
I recall.  I believe the newest official client for Windows 2000 supports only
MSNP11 and older, as well.  Although XP and Vista are making inroads into the
installed base, there are still a lot of users with Windows Me or earlier
DOS-based Windows OSes, and I don't think Microsoft is willing to anger quite
that many users just yet.  (Of course, only they know exactly how many MSNP9 and
MSNP11 users they actually have, and on which Windows versions.)  We'd also
likely get advance warning and a hard cutoff date, just like we did when MSNP2
was decommissioned as described above.  I'm also willing to bet they'll cut the
cord on P9 and P11 at the same time, if they ever do.

In short, while supporting a newer version of MSN's protocol is important, I
think it's safe to say that we still have forseeable life left in MSNP9.

Stu, Ka-Hing, or anyone else knowledgeable in this area, please feel free to
correct any factual errors or faulty memories on my part.
