Text Editor and SSI

Hello every one. If you go to the frontpage of my new VSHARE site (http://www.video4realestate.net), I have added a new window in the middle of that site, which needs to be edited often, called: "Video Introduction".

I would like it be be edited through the text editor that is build in with the vshare script. I could add that section with a SSI.

I need to edit often enough that the client won't have to learn html, or for that matter php.

At least to let me know or guide me how to do it. Is that possible?

Thanks,
