Scrolling the text at any faster than a blur is counterproductive for 
the user, after all.  You're off by a decimal, though, an 80-column line 
at 20ms is 4kbytes/sec.  My guess is that any faster throughput than 
10kbytes/sec is getting amusing for a mud, which in theory intends for 
most of this text to be read anyway.

That looks quite good, except that Trolltech doesn't yet have a GPL-qt 
for Win32.  I might take another look at it whenever qt4 comes out, but 
in the meantime (since I'm unfortunately developing on a win2k system) 
it's not useful.

See the scrolling problem in the original post, as to why I can't use it 
as a temporary user interface. :)
