I would like to see a slideshow feature in the MLON protocol.

My proposal would be, to allow the command issued for a "showBigArtwork" item to return an array of image urls instead of a single URL.

Today an item for "showBigArtwork" looks like this:

{
	actions => {
	  "do" => {
		cmd => [...]
	  },
	},
	showBigArtwork => 1,
}

and the "do" command returns

{
   artworkUrl => "http://...",
   offset => 0,
},

or

{
   artworkId => xxx, offset => 0
}

Apart from this not being conformant to this specification:
http://wiki.slimdevices.com/index.php/SqueezeCenterSqueezePlayInterface
which clearly states that an "item_loop" is a required field, this limits the response to a single item.

This enhancement request is to supply

{
   count => n,
   item_loop => [{
           artworkId => xxx | artworkUrl => "http://..."
       },
   ]
}

instead, the Controller (and iPeng, SqueezePlay...) can then decide whether to use only the first item or play a slideshow.
