Hi Jeff,
That's definitely a Tom Goddard question, but he is away on vacation  
this week.

Pending a definitive answer, I am guessing it is not in the plans.   
However, I believe you can do what you want by resampling the data on  
a differently oriented grid, and then using the "Planes" feature on  
that second, resampled set of data.  You would generate the resampled  
data using the "Subregion selection" feature of Volume Viewer, by  
turning on "Select subregions..." with the mouse, and after drawing  
the selection box, turning on "Rotate selection box" and change the  
orientation as desired, then clicking the Resample button.  This does  
not mess up your original data, just creates an additional, resampled  
data set.

Downsides are that it may take some coordination or a couple of tries  
to rotate the box as desired, and resampling causes some loss of  
resolution.  It may be that resampling is necessary for showing  
arbitrarily oriented planes, however, even if such an option were  
added to the GUI.

I hope this helps,
