Is your proxy in public domain, GPL or whatever? :-)

RFC2222 was written in 1997, and now 1999. We still do not have
common SMTP authentication. Yes, everything above CAN be done, but
it's too complicated for an average programmer, and there are a lot of
assinine problems with strong encryption like U.S. export troubles,
prohibited strong cryptography in Russia, etc, etc. What we really need is:
1. Simple SASL implementation in public domain, available to everyone
without any restriction (quite probably it was done alredy),
2. Easy to use proxy for end-users, speakin this particular SASL, and
3. Someone who will patch every popular MTA and bugger MTA authors
to include these in the standard distribution. You know, 99.9% of mailers
work in their default configuration...
This problem can be solved only with complex actions -- both
programming and lobbying particular implementation (I don't like
the idea of free-for-all authentication methods -- Micro@&#*^$ will
come up with their own for sure). And lobbying is much more important...
