I've been thinking that might not be a bad idea.  Perhaps some sort of 
updateMetadata method?  Together with an editableMetadataEntries 
property (since, for example, mpris:length is clearly not going to be 
editable, and the same may well be true of other things).

method updateMetadata(in a{sv} updatedEntries)
  - to delete an entry, send an invalid variant

property as editableMetadataEntries
  - list of metadata entry names that can be edited
