Thanks Eric, for the well informed opinion. What it comes down to I suppose is more investigation and a better Idea of what exactly I want to accomplish.
My approach has always been to start minimulist and build from there. I've found that it's easier that way. I can't say for sure which way to go yet, I'm still leaning to DOS because I don't see a need for a multi-user system. I will keep your advice in mind when the decision is made though.

DOS programs which use the internet are usually LINKED TO a TCP/IP stack. That means they have direct and exclusive access to the stack, and moving the stack into the kernel will not improve anything at all. Only for multitasking operating systems there would be a difference. > I think we've all read about the Apache -vs- IIS > debate for years.

There are fast kernel-space web servers for Linux, too, just google for them. > loaded FreeDOS on my old 366 MHz Compaq and it boots faster than any > other computer I own. My main Linux PC has been an 133 MHz one for years (secondary one being a 75 MHz at my parent's home), fast enough even as an mp3 streaming web server! Plus you can install Linux versions with slimmed-down C libraries (libc / ...) on computers with as little as 4-8 MB RAM. I myself have installed a very normal (old SuSE) Linux on a PC with 16 MB RAM (1 MB of which was reserved as VGA RAM) and even using the GUI worked. So I see no point at all why you would want DOS on a turbo fast 400 MHz embedded server! Remember that Linux is a native networking OS with multi- tasking and multithreading, while DOS webservers like EzNOS only use limited TCP/IP stacks (1 task, at most 3 connections at the same time). The WatTCP and Watt32 stack libraries are probably better (they are free, but if you want the handbook, you have to pay) - so try those if you still want DOS network server programming. Advantage of Watt32 + DJGPP compiler is that the libc of DJGPP (which is a clone of the Linux libc, and DJGPP itself is a clone of gcc / gpp!!!) is able to use long file names directly (you need to load the DOSLFN driver, though, or use the experimental kernel with builtin LFN support).
