One can build a stackless kernel for linux. I've done it. Using make menuconfig, or make xconfig, whatever, remove TCP/IP support from the kernel. May as well remove the other transport layer choices as well. You will need a new ifconfig. I built mine as well as other utilities using the net-tools packages. I have heard that newer releases of RH will provide this without using net-tools. This is at the heart of hogwash in stealth mode, see: http://hogwash.sourceforge.net/ and find the writeup by Michael Karagiannis listed the main page under Stackless Hogwash Howto.
