I think there is a world of knowledge and possiblities in OO in LV. Just look at all the different implementations (by reference, by value, LVOOP, GOOP, Endevo, etc., etc. ). The whole topic is overwhelming and a little intimidating. Some of us are still a little too nervous to jump right in simply due to the number of choices. I think it would be good if NI took the lead (hint hint) and really worked on some training material in OO programming and the native LV OO implementation. If NI leaves it up to us we will only offer only more choices and implementations. This will lead to a handful of gurus and the rest of us scratching our heads or paying someone else to do what we should be able to do on our own if we only had just a little more info ...
