Kodachromes will withstand 1-4 hours of projection depending on projector 
factors: lamp intensity and how hot the slide gets.  Ektachromes will 
withstand 2-6 hours depending on the same factors.  The measurement 
standard accepted by most is about a 10 0.000000ade in the color layer most 
susceptible to fading.  Ektachromes are not that much better.  I don't 
believe any of my most used Kodachromes for family slide shows have seen 
even 15 minutes of projection.
For continuous loop or a canned slide show that will be given frequently 
(on the talk circuit ??), use slide dupes and keep the originals archived, 
whether it's Kodachrome or Ektachrome!!
