The Windows Live Messenger Web Toolkit enables you to build Web-based applications that integrate with Windows Live™ Messenger. With the Windows Live Messenger Web Toolkit, you can build presence-enabled instant messaging applications that Web site visitors can use to interact with each other and with other Messenger users.

Requirements
The requirements for Windows Live Messenger Web Toolkit usage are as follows:
-
Each user must have a Windows Live ID. A user does not need to be a current Messenger user; however, a Windows Live ID is required for signing in to Messenger using the Windows Live Messenger Toolkit. A user can obtain a Windows Live ID by visiting the Windows Live ID site. A Hotmail® or Windows Live e-mail address is not required to obtain a Windows Live ID; you can use any kind of e-mail address.
-
Users must grant permission to each Web site that hosts a Windows Live Messenger Web Toolkit application. The Windows Live Messenger Web Toolkit automatically handles requesting the user permissions where applicable.
