I don't think that Poser is running up against any 32 bit limits that going to 64bits would help (unlike my own work in acoustics). So "support" of 64 bit Itanium or Sledgehammer really is just a matter of compiler optimizations, and is a job for the compiler writers. Since it's ported Mac code anyway, don't count on too much optimization. As far as the dual processor stuff, you have no idea how difficult taking advantage of SMP is. It requires a program which is written specifically to be able to break a task up into multiple, parallel tasks, and shepherd the results of this splitting. And considering how different Mac and Windows do this, you would have to do double the work. At best, all it would do is speed Poser's rendering a bit. Good OpenGL support would help a lot more, with the actual posing. And Whistler's "problems dealing with dual processors" will probably clear up when Apple actually starts pushing the (now 12 years late) Os-X.
