This has been brought up numerous times. Paul said it won't happen because bandwidth and some other stuff I can't recall.
It is because what he's requesting isn't a
real instant messenger.
There will be a standalone application released hopefully soon (it's basically done). However, doing a hacky fake IM thing like FB is horribly ridiculous. All it really does is refresh your page every second without you knowing it. It's a huge waste of bandwidth on both the server and client. Once web pages support truly persistent connections, then it will be added, but until then, I will stick with a real application that does it properly.
Oh, and there are 7,187 people online the dIM right now, and 78% of them have been connected for over 24 hours. Peak usage in the last 48 hours was a little over 10k. Many people use it on a continual basis.
edit: Persistent connection means the server and client being able to actively talk back and forth, such as the server notifying the client of changes without the client requesting them. As in, a more typical tcp/ip application, rather than a one way poll->return data approach as how HTTP currently works.
