	There's a newer copy of the UnterSource on decuac, for FTP. I'm
not going to argue about the relative merits of various server I/O libraries,
but the Unter library (briefly) supports:

	* incoming packet combination into lines
	* stripping data into lines as it comes in [the network layer handles
		the grot of making it look like the server is getting a line
		at a time input]
	* VMS multinet plug-compatible version
	* WHO lists, and hooks into logged-in-user matching
	* idle time
	* fairly efficient [the network is the bottleneck, as Sun would say]

	It's in the UnterSource distribution, in umud/net_bsd.c and
umud/net_vms.c The calling interface resembles roughly:

	io_init();
	while(io_loop())
		io_sync();

	where io_loop() has some function that is expecting to be handed
input a line at a time.

	Output is handled with a varargs-based "say" command, which just
takes a list of strings to send:

	say(who,"this is ","a test",some_string_pointer,"\n",0);
