So far, SkippingStones supports notification of SMS and calls as well as controlling the music player. Please note that for the music player functionality to work you need to manually apply an additional patch as described in my blog post you linked above. Also note that, right now, the call notification also triggers when dialing a number; i.e., it also goes off for outgoing calls too. Furthermore, there is no "daemon" mode yet; i.e., you will need to keep SkippingStones open "all the time" (or at least as long as you want to use the Pebble with your phone). As you already noticed, the last update on SkippingStones was about two months ago. Unfortunately, my time is very very limited, right now. Thus, it is rather unlikely that there will be any enhancements if no one else joins in.
