FYI, in FTP servers, Mode Z is used for ZLib'ed (deflate) transfers. The 
client sends the Mode Z command and the server decides to apply the 
compression for download object either by the coefficient it decided on its 
own or by the again client's OPTS command. You will need to modify 
SendNextData for downloads.

I can send you code snippets if you would like to have. Just check out 
http://www.fastream.com/netfileserver.htm and let me know if this is what 
you have on your mind.
