If only we could click our fingers and turn back time... without loosing all the effort done during that time.

Yes this make sense. In terms of reuse it might limit us. Although perhaps one could take a builder plugin approach to constructing scene graphs. >> I ask these questions as I'd expect many others will be in a similar >> position.

Even if one only learns from it it would still be a useful thing to review. Do you have a timeline for when it might be open sourced?
