Visual Technology and XPI are jointly developing an X Server terminal,
which qualifies as a "smart screen handler".  Also, I've worked with
systems which do some fairly high level things.  For example, you can
download a set of characters and a column number, and the reading
process won't be unblocked until either a character in the downloaded
set is typed, or the column number is reached.  This is useful for
programs like Emacs, to avoid context switches on every character
typed.
