I did actually do a post on the bug tracker, some weeks ago, but I think the Idea I was working on was not completely understood. Actually I did not understand it completeley myself either, before the end of the project. (In this way may explanations of the idea was maybe not to good.)
What I was trying to find out was if I should open the old bug tracker item, or open a new. I think I open a new one, as the "idea" somehow has changed from the original post.
I think I will try to post a new feature request in the bugtracker and post a some kind of "howto" that explain how things were done. Than possibly some of it can be used. (It is actually technically tree different smaller modificiations combined together to obtain an end ressult.)
