Collaboration (multimedia based) is a business tool
Downloading (or streaming) your CEO's quarterly report (MP3, other type?) to your BB is a business activity
Downloading your voice message (wav file) from email (unified messaging) is a business activity...
One can bundle an eOffice like application (arrange and save files on BB) with a javazoom app. and a UI to deliver the end result. Content not quality (e.g., high quality audio) matters...
I am not a SW designer, but I see a business opportunity
