 ?] No thanks.
Abort.

BTW, kickass work on apt, Panu. You have first dibs on my firstborn
child. If anyone wants to play with aptitude on Fedora, which already
supports the exact feature this thread is about, I've made up a package:

http://www.haxxed.com/rpms/aptitude-0.3.3-1.src.rpm
http://www.haxxed.com/rpms/FC5/aptitude-0.3.3-1.x86_64.rpm
http://www.haxxed.com/rpms/FC5/aptitude-0.3.3-1.i386.rpm

On FC5 you will need/want apt from the extras-development repo, which
supports multilib and yum style metadata.
