We also haven't set it up under 1.8 because of that cautionary
statement, but I've heard a pretty good explanation of that 
statement.  (Better than I can describe it.)

AT/TLS supposedly works under 1.8, but the 1.8 Tn3270 and FTP
servers are not AT/TLS-aware until 1.9.  They can't tell that they are
running under AT/TLS so you cannot cleanly move their TLS support
into AT/TLS.  I think I heard that you actually *could* move it into
AT/TLS, but that you'll have to change it again when you get to 1.9 
or later.

It sounds like you can implement 1.8 AT/TLS support for other
applications but we haven't tried.

I'd be interested in hearing that, too.
