请教DELPHI自带的例子 NETCHAT的问题(50分)

// create thread
DataThread:= TClientDataThread.Create(true);
// set the TagetList to the gui list that you
// with to synch with.
DataThread.TargetList := memRecv.lines;
// Load the Threads ListBuffer
DataThread.ListBuffer.Add('*** Connection Accepted ***');
DataThread.ListBuffer.Add('Remote Host: ' + ClientSocket.LookupHostName(ClientSocket.RemoteHost) +
' (' + ClientSocket.RemoteHost + ')');
DataThread.ListBuffer.Add('===== begin
message =====');
s := ClientSocket.Receiveln;
while s <> ''do
begin
DataThread.ListBuffer.Add(s);
s := ClientSocket.Receiveln;
end;
DataThread.ListBuffer.Add('===== End of message =====');
// Call Resume which will execute and synch the
// ListBuffer with the TargetList
DataThread.Resume;
2个问题：
1，这个例子里面是客户端向服务端发消息，如果服务端要返回消息应该如何做？
2，如果程序写的复杂些，同时有10个客户端向服务端发消息，服务端是每接受到一个消息就创建一个进程，还是消息在队列里面自动排列呢？
请大家点拨，谢谢
