Oh well. so much for this one..but it's a start. I tried playing my lastfm library through the embedded Centrafuse web browser and it ends up launching the Scrobbling client that I downloaded and installed. So maybe a simple plugin that embeds the LastFM scrobbler that would be perfect. The buttons on that scrobbler are by default large enough for using with a touchscreen. I hope someone or the original plugin creator revisits this thread and enhances the plugin.
