Ludovic, It should be fine to pose your questions in multiple forums, as long as you clearly identify and cross-link (as you have). StackOverflow is becoming popular, and Claus has even answered several of my questions there. It's the "blind" cross-posts without reference links that become annoying because they can result in duplicated efforts.
As-for the technical core of your question itself, I defer to the committers. ~ RNPG
