There is nothing wrong with changing an executable with e.g. sed.

It is very ugly, yes, but it does work.

The qkhack for Quake worked in this way. It changed the name of some
libraries, thereby changing quake's mouse and keyboard input from using
svgalib to using X. (With a bit of wrapper code in a special dll).

However, as someone pointed out, it is as easy for the downloader to
change the binary back - if he can find the code in the binary, that is.

You know you're a Linux geek when...

    You feel an undefined sense of shame when the advice you give on
    Windows 9X works.
