Hi Shamun,

you absolutely want to use VB!

It has a strong, responsive company behind it, you can always turn to in =

times of need, the community might be a way better fit for your =

all that. VB! Or, of course, Java maybe.

Hi Jose,

I just tried Luabind + lua 5.2 -- doesn't compile (due to function

to port SLB to work with lua 5.2?

Thanks!
