I am looking at my own comments further down - which I also sent directly to Mindola - and wonder why we don't see any development on this product. Is the vendor not interested in increasing the capabilities of this product? I trust that this must be a good decision based on time/resources, alternative projects and projected ROI.
In any case, I want to now recommend Signal from Alloysoft over PatioTunes. Especially if you own an iPhone or iPod Touch and want to remote control your home's iTunes installation from your patio ... give Signal a try. Their demo is fully working, just displays "please register" for a third of the library content.
One feature I like is that I can change the rating from the remote - something I asked to be included in PatioTunes 1.5 years ago. *sighs*
