In terms of multiple simultaneously *installed* versions, I consider it 
an absolutely essential feature of any *good* package manager (This is a 
big part of why I hate most system-level Linux package managers, 
including the one on my own machine). But the idea of multiple versions 
*within one program* is indeed interesting.

Doesn't strike me as something you'd want to frequently take advantage 
of, but having it there as a viable workaround for when problems do 
arise could certainly be quite nice.
