Plugin for Genealogy Site: Suport Gedcom export

Hey Fellas,
I’m building a genealogy site for my family and i have found a number of excellent plugins for this purpose, my preferred choice being rootspersona .
However, I can’t find one that will let me export Gedcom files.
This is rather a problem as I want to be able to; a) backup my research, b) allow others to coordinate their research(aka work on the site and not make me have to update my local copy manually and vice versa), and finally c) be able to offer a copy of my research as a download.

I have done some digging but my searching has not turned up an option as of yet. And yes before someone asks, I am looking at free plugins for the time being.
Thanks,
Dirty Lens
