It may not have anything to do with the network side of things, but it has everything to do with your server executable. My gopherd, Xylophar, doesn't know it is a piece of network software, for example. Xinetd calls it and it accepts the request via user input and this is limited by the programming language. Other gopherd's accept the request as command line arguments and this is limited by the shell it is running under. There are infinite ways to skin this cat. Otherwise we agree.
