Hi Al,

re: v5 - are you thinking of Rhino? I'm still working on finishing up MoI v2 right now, so MoI v5 is quite a long ways off.

Right now I do not plan on having a 64-bit version of MoI anytime soon, it adds a considerable amount of work to maintain and distribute multiple versions.

For the foreseeable future MoI will remain 32-bit. The 32-bit version runs fine on 64-bit Windows though, and there is actually more addressable memory available to the 32-bit version when running on 64-bit Windows as well.
