Here is the first release of NetDog, a light weight version of NetCat. NetDog(or nd) is coded by me, Chroniccommand. If you take a look at the readme, you will see this is not supposed to be used over NetCat. It is merely a light weight solution using Python sockets.
Here are some screenshots:
NetDog main help screen(no arguments given):

Listening on port 1337. This is buggy and probably won't work. Good luck :P

Anyway, here is the tar ball of NetDog:
http://poisonhack.info/netdog.tar.gz

The tarball includes all files needed to run NetDog on a *nix and Windows system. For *nix I've included an install script, which you need to run as root. Then you can just run netdog instead of running the pythong script.

Enjoy. And please, please read the README.
