How to receive push notifications in Windows 7\XP in your program?

Question

Push technologies

Is there an analogue of push notifications only for Windows 7\XP, preferably in Delphi. I know what is under Windows 8 for metro styled apps, but for regular Windows? That is, to always keep a cheap connection without loading the server.
