Gives you a shortcode to embed a Wave in your WordPress page/post.
Kind of... There is a button to press above the edit box, but it still lets you change all of the options.
The shortcode supports the id attribute which is required, plus the width and height of the div that it embeds, plus all of the options that are available to setUIConfig in the wave embed API.
Yeah. About that. I don't have an official Wave account yet, so how could I possibly begin to test with other Wave servers? No, but really - if you can get me an account on the Wave server you want to see supported(and preferably supports Google's embed API), send me an e-mail or something.
