My wife and are getting palm centros (http://www.palm.com/us/products/smartphones/centro/) and I also have an old palm zire 72. Both of these have bluetooth and IR, but no wifi. Most of the software I've seen out there is for IR and as a lot of my AV stuff is behind me and somewhat hidden (using a projector) I'm wondering if there's someway I could use bluetooth along with my home theater pc to control everything. Any advice out there? It seems like palms could be a great platform for home theater control.

This looks pretty promising...

Looks like you can create your own interfaces and map the buttons to corresponding keystrokes on the pc. I'll have to play with it when I get home.
