I'm quite hopeful about this development. If we have anything for the
network in D2, that would be great, and integration with File will reuse
a ton of work.
I'm considering extending Adam an offer to join Phobos. He has donated a
Windows machine for building and running Phobos and generally seems to
know what he's talking about. If he'll join the project, my hope is to
attract him to dedicate more time to it.
Please cast your vote by replying (silence = abstaining, i.e. you're not
for or against).

I've written a small module that opens a network connection, then wraps
it in
the File struct, allowing you to use the byLine, etc., ranges on it, as
well as
writef/readln/etc.
It is Linux only, but should be pretty easy to port to other operating
systems.
Ideally, I'd like to eventually be able to use File for talking
to processes too, on all D platforms.
Here's the code I have for now:
==============
public import std.stdio;
import std.string;
import std.conv;
version(linux):
import std.c.linux.linux;
import std.c.linux.socket;
alias std.c.linux.socket sock;
alias std.c.linux.linux linux;
enum int PF_INET = 2;
enum int AF_INET = PF_INET;
extern(C) FILE* fdopen(int, const(char)*);
File openNetwork(string host, ushort port) {
hostent* h;
sockaddr_in addr;
h = gethostbyname(std.string.toStringz(host));
if(h is null)
throw new StdioException("gethostbyname");
int s = socket(PF_INET, SOCK_STREAM, 0);
if(s == -1)
throw new StdioException("socket");
scope(failure)
close(s);
addr.sin_family = AF_INET;
addr.sin_port = htons(port);
std.c.string.memcpy(&addr.sin_addr.s_addr, h.h_addr, h.h_length);
if(sock.connect(s, cast(sockaddr*) &addr, addr.sizeof) == -1)
throw new StdioException("Connect failed");
FILE* fp = fdopen(s, "w+".ptr);
File f;
auto imp = new File.Impl(fp, 1, host ~ ":" ~ to!string(port));
f.p = imp;
return f;
}
