Allow supression of metadata to connected clients but not to YP listings

An odd sounding request I know..

I was wondering whether it would be possible to add an optional parameter to mount-specific settings to prevent metadata being sent to connected clients... but still allow metadata updates to be sent to YP directories.

This request is based on the ever increasing problem of streamripping; we can deter these people if we can configure whether or not to present metadata to connected agents. I am not aware of any streamripping software which can trawl YP listings or otherwise to split tracks, and I still think YP listings for metadata has a very valid purpose.
