Windows Live Messenger

Hi all. I've seen official WLM Apps for Nokia phones, BB phones, etc. I'm looking for an official WLM for Android here in the UK. Is there one?

All there seems to be is Meebo/Nimbuzz/eBuddy/Palringo, but they all sound quite dodgy because they are third parties. How can I make sure there aren't people at Meebo or eBuddy or hackers getting at my email and password and deleting all my contacts/emails or something?

I understand that there is an official WLM App for US Android phones. Can't someone just copy that App and put it on the marketplace for everyone else in the world to use?
