Agreed.  And Apple provides a command line tool, 'lipo' to merge things
together as you describe.

Agreed.  Which is why I'm starting this discussion sooner than
later. :)  Is it something kitware wants to eventually support?  From my
point of view, being able to build vtk as universal is far far more
appealing that having to have 2 machines and lipo-ing together.  Have
others in the past not wanted to cross compile vtk?  Is this the first
time it's come up?
