Does anyone have any experience working with Facebook Markup language?

I dont have a facebook account and I only use FB to make banner ads for clients

Basically FBML allows you to add additional tab/links to fan/business pages

Should be fairly straight forward but when i googled for info they are saying that FBML is going to be deprecated and i will have to use an iframe (Barf what is it 1995 again) and their javascript SDK and social plugins.. Thye make you use and iframe and their SDK to put your app in a sandbox where (supposedly) they can manage processes and protect their users.

Meh, I only basically need to be able to create a static page so I can probably figure this out.... but thought I would see if anybody on here has ever messed with it.
