nomuse - I'm not saying anymore about the number of possible combinations other then it is very large. Sticking my foot in my mouth twice is quite enough for one day, thank you. ;) As to a "guided evolutionary process" in a way that's pretty much built into the process. With the rotations controlled by max and min limits it's a simple task to alter the range of the results. With it only taking a minute or two to do a run and with the limits being available for change on the GUI, doing multiple runs to tune a pose is a good solution. To everyone that posted - Thank you for your comments and encouragement. Now all I have to do is get the thing finished so it can be put to work! :)
