I think Artist Slideshow needs to continue to recognize the " / " divider (including spaces) as that is how the XBMC library recognizes multiple entries in one field by default:

For many categories, such as genres and artists, XBMC supports multiple values in the one field. By default it uses the character sequence " / " to divide the entry into multiple values. This divider may be changed via advancedsettings.xml.[/i]

Good enough. It looks like I wasn't following the spec before anyway I'll try and fix that in the next week.
