It seems much more justifiable to me to put support libraries for "legacy" applications somewhere "off the beaten paths". IOW, provide a libVLC that's specific to KDE4/Qt4 applications and that lacks the gui plugins. BTW, does phonon-backend-vlc use libVLC for anything other than audio? If it doesn't, wouldn't it be possible to build a dedicated libVLC that's stripped of everything that won't be used and installs its plugins in a different location than where VLC looks for them?
