I couldn't get the kmplayer flash player to load pandora's swf in less than 5 minutes (see flashpandora.zip). I did make a version that can be loaded in the browser (see web_pandora.zip). But it takes about a minute to load, prompts you about security (click OK) and then sucks ~70% of the cpu playing the songs. That will kill the battery too quickly. No matter, lastfm works fine.
