Are you developing the ability to allow streaming to mobile devices like the Treo or iPhone or others? I use a Sprint Treo 700p (Palm OS), and stream all kinds of music regularly on sprint's EVDO network, works great. The main hold up now is the requirement for using version 9 of Adobe's flash player in order to stream. There needs to be a flash player or other method to facilitate the stream that is secure enough for your needs and allows access by mobile users.
Thanks,
