Audiobook Support and RSS questions

I've been reading everything I can find to see if I can make this work.

I am setting up a media server that will be accessible to my family.

I plan on using Calibre, as I already have it setup with my e-book library. I will turn on the web server ability so everyone can view it on their PCs and phones.

What I want to know is if there is a way to publish an RSS feed of books in the library?

I want to create a library of my M4B files and publish each book in an RSS feed that I can put into a podcast app to be downloaded as podcasts.

This will be the easiest way for my extended family to access these audio books.

So...:help:
1) Can Calibre offer-up m4b files as a book format?
2) Can Calibre publis RSS feeds for a book?

All I have been able to learn in my searching is how to "harvest" data from RSS and compile it into a book format.
