So this plugin appears to be incomplete or not functioning as you may expect. It would not even connect to my lastfm account until I downloaded and installed the scrobbler from lastfm. Then it managed to load my last played track but it won't play. I can't seem to get any tracks played nor figure out how to load my profile. I may have to play more with that XML..we shall see.
If anyone that knows how to code the Centrafuse plugins you might want to take a look at this one. The original submitter of this thread appears to have fell off or has forgot about it.
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.
