There was lots of debate on the Mesh Deformer and whether it should have a single default shape as the basis for deformation calculations or whether it should have multiple base shapes. That question is still undecided. Discussion has kinda died down, at least in my circles.
If you are unaware of the sides of the debate, see: The Great #SL Deformer Debate.

Questions
One of the prime questions I asked in the article is how it will be funded. That is not likely to be a problem.
Another problem is what it would cost to add the capability. Emma Gilmour asked Qarl what it would cost, not that much. We are certain we can raise the needed money in a very short time. We have almost half of it covered now.
So, a couple of questions are down and the possibility becomes much more likely.
And the Lab…
The next challenge is where are we with the Lab and Avatar 2.0?
