Thanks Ben,

I had a look at the Ingo source after my first message and I'm glad to  
say that I easily found the right file and that it is really quite  
understandable.

I've begun hacking at it and I have a version that seems to work.  
Needs more testing though, and I will have to port the modifs to the  
latest version (mine is Ingo 1.1.1).

If someone wants to give it a try before I'm confident enough to  
release it, feel free to mail me. I don't want to pollute the list.

Cheers
