Hey Matt,
Logitech has some cool media servers -  Squeezebox, Duet, and Transporter.  These devices are pretty incredible.  There are a bunch of apps for droid, apple (Ipeng, Squeeze Commander, etc.) taht allow you to control themand get metadata.  Having a 2 way Driver for RTI would be very sweet as the units are very inexpensive and are in a lot of households.  Having a 2 way driver would be great for installers as its an affordable and very versatile media player. The device does internet radio, Pandora, streams your music library. 

BTW  - Jim Felderman over at www.controlworks.com has a driver for Creston but is not going to make on for RTI.  There are allot of clients who have asked me about this so it could be very popular.

Thanks,
Patrick
