We (Chowmain Software) have just released a Crestron Home driver which doesn't require any hardware, connects immediately and provides controls for pretty much every app and has a list of apps (with app launching, favourites, etc).

When it came out we were asked for a SIMPL version as well, which we now how in the pipeline. The module itself isn't too hard, but I still have to write licencing code so I don't have an ETA just yet. If anyone wants to help us beta test though I'd love to get some help. Just let me know and I'll add you to the list.
