How can I incorporate LaTeX into an iBook created with iBooks Author?

I'm interested in writing a text in the sciences that requires some mathematical notation, but I see no way to incorporate LaTeX into iBooks using iBooks Author.

Am I missing a feature? Is there an add-on plug-in architecture (e.g. using "widgets") that would allow me to add a tool for LaTeX editing. Are there any existing LaTeX "widgets" or add-ons?

Ideally, I'm seeking something other than a "one-way" static PDF- or image-generation approach.

...is the solution I'll go with now. You can export your Latex as a picture which can be very easily copied into iBooks Author.
