Yes, they can.

However, this isn't really necessary (depending on the overall  
setup). Consider the output of

     $ which tex

which, on my machine, responds


Note the path. If I were on an Intel Mac, the "powerpc" part would be  
replaced by "i686" or something. So the binaries would be separate  
anyway. The two architectures can co-exist in a single filesystem  
even without universal binaries, by appropriate PATH configuration, etc.

Those who have been at WWDC this week are, of course, constrained by  
the usual NDA rules from saying much, but I think I can take the  
liberty of commenting that I see no reason to be concerned. :)
