Works great on my BlackBerry Bold... but can you add personal stations?

I'm a subscriber to DI.FM and would love to listen to the high-bandwidth feed on my 3G phone (which works great currently!) -- I can download at up to 100kb/s in many areas, so I know it'll support the 192kbps stream.

Is this a feature you guys could add to the site sometime? Personal streams that aren't published? (like with someone's own username/password)
