Can you afford the bandwidth?  Updates are already 2-3GB per year.  I'll say 
again; if Microsoft were to require 2GB per year to stay up-to-date people 
would be up in arms....

It's not even interface definitions.  It's whole languages.  It's whole 
libraries; GTK1.2 versus GTK2 or QT3 versus QT4, for instance.  Those are 
setup now to coexist.

To do this you need to keep all dependencies of all programs that you wish to 
do this with.  I would think there aren't enough packagers in the typical 
distribution's shop to handle that many packages.

Also, the upstream has to respect the multiple version capability.  Things 
like, oh, maildirs need to be intelligently addressed and not blindly

Multiple versions of everything....good thing disks are getting bigger...

That is probably the best we'll see.  But we also have to come to grip with 
the idea that there is no ideal Linux distribution; not just for all users, 
but even for all programs.
