Hmmm, there's a feature to update MSN Spaces with mail, right?
So you could make a plugin for WP that sends a mail(with the posts content) to MSN Spaces every time you add a post to your blog, that way, the contact card would be updated frequently.

The only problem is when the contact tries to open your site, you would need some kind of redirection code, which probably is impossible...
