Tidal support is coming along well just two big hurtles left i believe. The first is just time consuming and that is building controller for the BDP, although this is just going to take time and should poise any significant resistance in development. Second, is streaming, although streaming work the first 10 or 15 seconds is a little "jittery", but once it gets going its fine until the stream is interrupted by user interfaction (pause, next track, etc).
Will be releasing a Beta tonight for those interested in trying it out, just be warned this is by no means a finished product and won't be for a month or two. There isn't even an icon for it, you'll need to navigate to the page by url.
