Ive not actually seen it working or heard anything outside of news sites. Its supposedly going to work no matter what nintendo do.
I have the freeloader (waiting for SSBB to be delivered.) Its not that it will always work no matter what Nintendo do, its that it stops the games that update before playing from updating. It also says on the box that it may not be compatiable with future firmware updates.
My copy turned up this morning, but I haven't had chance to have a go yet with me being at work.
Im gonna have a good few hours on it tonight, will let you know what it is like after that.
