[Need Help]How to post a blog entry both to wordpress blog system and Microsoft Live Space?

I don’t want to write one post twice and post them to Live space and my own wordpress system one by one. Is there any good solution to write once and post once, but post to both 2 blog system?

Further more, if it could be implemented by Windows Live Writer, it could be the best plan.

Please tell me if you have any good solution.

Thanks in advance.
