Hm.  I just took a VERY quick look at the OpenSSL API tutorial, and
it actually doesn't seem terrible.  I abstracted a lot of buffering
code out when I did the SASL work, so I think with a bit of fiddling
it wouldn't be too bad.  I wouldn't call it "trivial", but I wouldn't
call it terrible.  A Google for "openssl programming" popped up a
few tutorials which covered what is necessary (it looks like you
can ignore 90% of the OpenSSL API).

Actually, I have a proxy server like that ... except that (as you might
have guessed) it implements SASL :-/

Well, the prime dismotivator is more "eh, I wouldn't use it" more than
anything.  Yes, I know gmail accounts are free, but the last thing I need
is another email account.
