Joomla JCE add custom component data to link browser

I am using Joomla 1.6 along with JCE 2.0.15

I also have created my own component and I want to be able to link to pages from this component and to be more precise, I would like them to appear in the link browser window:

Basically I just need to be able to let users enter links to stuff from my component to articles without forcing them to make a menu entry in a hidden menu for each piece they want to link to (which I now see as a pretty bad alternative).

I asked the developer of JCE the same question - the answer is you can do it, but there is no documentation.

As a guide he suggests looking at some of the existing 3rd Party Extensions for JCE 2.x as a guide.
