I use beamer in a similar manner, producing 4-up copies of the slide  
show by commenting and uncommenting short segments in the preamble,  
depending upon whether I am producing a version to show in class or a  
version to be distributed as lecture notes. The colors are altered as  
well as the number of slides per page.
