Is Prex an QNX demo on a floppy ?

I had a QNX demo on a floppy, with 1730 files of posix codes. It can set up the external modem to go thru a window manager and activate a html browser. You connect to your internet on a 1.44 floppy. It works even today, but the browser is inadequate.

Prex 0.4.1 is about 400kb. It can emulate posix. It can send an URL connection packet. Does it miss the dialup external modem setup? Does it miss the xserver for window manager and a better html and xml browser?

So, we have to boot into Prex and send packets to a Linux server on the internet, or a local xserver to use Linux applications?
