I looked for this annoucement on roottalk, but I couldn't find it, and
I don't recall seeing it - probably my mistake - could you point to
where it is?

That sounds good. Some questions (sorry and ignore if you already
answered the questions in the annoucement):
* Will in incorporate the STAR stuff?
* Will it allow for division of nodes, like in GEANT 3.21?
* Will it have methods like TNode::IsInside(const TVector3& r) const?
* Will it have the possibility of attaching electromagnetic fields to
a volume? And tracking parameters?
* Will it be something like the GEANT 4 classes?
* Could one possibly use the physics algorithms of GEANT 4 and/or
3.21, so that one could implment a detector simulation solely in
ROOT and not do all sorts of wierd loops to get GEANT 3.21/4 to
interface with the ROOT geometry definition?
