In this case, not *too* much of an effort:

$ rpm -ql sonic-visualiser
/usr/bin/sonic-visualiser
/usr/share/applications/fedora-sonic-visualiser.desktop
/usr/share/doc/sonic-visualiser-1.6
/usr/share/doc/sonic-visualiser-1.6/COPYING
/usr/share/doc/sonic-visualiser-1.6/README
/usr/share/doc/sonic-visualiser-1.6/README.OSC
/usr/share/icons/hicolor/48x48/apps/sonic-visualiser.png

but yes, having a Conflicts: should be good enough. In this case, I
should not be using Obsoletes: and Provides:, right? Unless there are
other packages that depend on sonic-visualiser being installed, that
could make do with sonic-visualiser-freeworld.

The other concern is legality. I'm currently based in the US, so ... not
sure how much I can do this myself.

Thanks,
