Actually it's been done. I rack my brain trying to remember the name of the mud, but I cannot. Anyway, it basically had a status bar at the bottom with your vital stats, and this was protected from screen scroll. Anyone know what mud im referring to? this is not some new thing-- the mud in question was around like three quarters of a decade ago (was diku derived)

Presageful, have I gazed upon the bars,
To watch that fluttering stranger ! and as oft
With unclosed lids, already had I dreamt
Of my sweet birth-place, and the old church-tower,
Whose bells, the poor man's only music, rang
From morn to evening, all the hot Fair-day,
So sweetly, that they stirred and haunted me
With a wild pleasure, falling on mine ear
Most like articulate sounds of things to come !
