Maybe for *your* applications, but for us 9600 baud is the limiting
factor much of the time. You should not be so presumptous about
the nature of the data being sent: try sending a 512 x 512 x 8 bit
image at 9600 baud! TeX ouput that uses DVI bitmaps rather than the
built in PostScript fonts is also frequently transmission-bound
rather than compute bound.
