The original boxless Slingbox, Orb might just be unveiling an iPhone/iPod Touch version of its excellent-and-free interface in the next couple of days.
Orb has apparently found a way around Apple’s RTSP port cockblockery by streaming your goodies as MP4 files. You’ll also be able to use Orb features with Winamp to "turn your home media player into a very limited kind of on-demand radio station for friends," according to The Register.
If this works well enough, the limitation of the storage space on your iPhone or iPod Touch could turn into less of an issue, since you’d be able to access all of your music and videos from wherever you can get a signal.
