have a look on arch-linux' pacman, which is more advanced than apt-get and
can therefore handle this problems.

basically you only have to be able do differ between packages which are 
instaleld as a dependancy and
packages which are installed by user demand.

if the user now wants to uninstall <foo>:
- remove everything depends on <foo>
- remove <bar> which is a dependancy of <foo>
    unless:
       - <bar> is needed by another programm
       - <bar> was installed by user demand

and everybody is happy.
