This sounds not overly wrong as it would reduce some possibly
needless duplication and reduction in diskspace.

On the other hand, I am not really sure it would be worthwhile.
On the machine in front of me I have e.g. /usr/bin/designer-qt4
(symlinked via /etc/alternatives/designer and /usr/bin/designer)
with 422584 bytes, assistant with 965092 etc. So the total "shared"
set is in the single digit MB range per installed version of Qt
(minus 1). 

Is this really worth the hassle compared to putting everything
into the same sandbox?
