Unfortunately, it's not terribly easy to do.  It appears that the escape
sequence for hpterm embeds the length of the string that's to go into the
title.  The usual xterm titlebar hack, however, pretends that the title
bar is a terminal status bar, and termcap and terminfo expect that there
are fixed strings for entering and leaving the status bar area.

There are two approaches I can think of that will work.  One is simply to
hardcode the string.  If your username is always, say, "judd", than you
could just use:

  termcapinfo hpterm 'hs:ts=\E&f0k11DHello judd!:fs=:ds=\E&f0k11DHello judd!'
  defhstatus "It doesn't matter what you put here.  This string is ignored."
  hardstatus off

The other approach would be to use the backtick command to generate the
entire escape sequence.  Have a shell script that looks something like
this:

  #!/bin/sh
  ARGS="$@"
  LENGTH=`echo "$ARGS" |wc -c`
  LEN=`expr $LENGTH - 1`
  echo "\033&f0k${LEN}D$ARGS\c"

Let's say that script is named hpterm-title.  You would then put this in
your .screenrc:

  backtick 31 86400 0 hpterm-title $LOGNAME
  termcapinfo dtterm 'hs:ts=:fs=:ds=\E&f0k0D'
  defhstatus %31`
  hardstatus off
