-)) Metropolis Grid now has at least 2 regions running and testing 7.5 with Bullet physics. My friend Judy from Hobo Amusement Park in sl is there. [shameless plug for her cool Park intentional]-))
She informs me, as we do know, the next iteration of Bullet should be, we hope, nicely improved, but it is very promising. As I don't know or understand the specialty of scripting I can't comment much on it, but I do know it is fun, even now-))
I am also told that the Aurora physics is very nice-))
[is there a closed thread:P?]
