How to get the list of online users on Live Messenger through PHP?

Question

Is it possible to get a list of connected users on msn throw php without using an additional application running on the server?

Basically I don't use msn but sometimes I need to talk with somebody and I need to know when he/she get online to talk and I would like to leave a cron that checks if that person is online. (sometimes I'm not at the computer but if I receive a mail I can try to get one)

Thanks for any response :D
