Windows Live Messenger can be embedded into a web page. This feature seems to have arrived in November 2007 based on the flurry of blog activity.
Embedding a messaging window is rather simple. To do so, you just need to change your Web Settings for your Windows Live account. Once you agree to expose your Messenger status, you can then select one of three embedding choices: full messaging client, a button or just an icon. The details are available from Microsoft but it pretty much just a matter of copying the generated code and pasting it into your web page.
