I would like to see RadioRoku support local radio streams. Here in Australia, most ISPs offer their own radio streams which are retransmissions of existing streams available on the Internet, like Virgin Radio. The main advantage of using the ISP provided streams is that they don't count towards your quota (virtually all broadband plans in Australia and many other countries have data transfer quotas).
Yes, I can add some of my ISP's streams to my presets, but there are only 18 presets, which would only hold a small fraction of the streams I would like to store.
If it was possible to store stream URLs as favourites, that would be perfect.
