There was a *very* slow unzipper 
for CP/M, but the current 
compression scheme (inflate/deflate) 
couldn't be implemented in a 64K 
memory space without a fancy and 
slow (especially on 8-bit hardware) 
disk swapping algorithm.  Unzip for 
CP/M-80 is not practical, CP/M-86 
should be no particular problem for 
somebody who actually cares to port 
it.
