    A professor that used to be here at CMU, put data compression firmware
into Concept 100/108 terminals.  His name was Leonard Zubdkoff, thus the
terminals became Concept-lnz's.  There is a technical paper here, but I have
never read it and I don't know if he published any official paper.  If any one
cares, send me mail and I will see what I can dig up.  Unfortunately, I don't
think that the I/O drivers use this feature and I think the only program that
actually takes advantage of it is Gosling's emacs.  It may not be that
helpful for a software approach, but the algorithm used may be able to be
applied in software.  I imagine it uses some variant of Lempel-Ziv, but I
really don't know.
