Raw sockets support must be removed (and was) just because of this: any application, in user mode, can write raw packets. Its is UNACCEPTABLE. Its totally against any network project
After that removal, you can write an application to write raw packets, but:
a) you must be in kernel mode and direct access to hardware
b) you install a library that do so

On *nix, you cant write raw packet at your will. You need to have priviledges to do that.
Problem on Windows is MS removed that priviledge need when turn available "raw packet" support. Now MS fixed it. Thanks God.

Im suprised that some ppl here NEVER give a greenie to MS, even when MS recognise its problems and fix it.
