Ah, upon reading it further, I guess I did misunderstand how it works.
I’m looking for a cookie-based pop-up that would appear the first time a visitor comes to the site (which this does beautifully), but also to have a clickable link in the menus of all pages that allows me to show a modal dialog with Contact Form content.
And on another page, a pair of links that would bring up modal case study pages. (So on that page, technically, I’d have three links that trigger modal dialogs.)
Looks like the beta allows for different selections of content in one modal dialog, based on jQuery code passed to the dialog.
Oh, I might have misunderstood – it looks like this discussion references it:

Did I read it wrong?
