PSP As Multimedia Remote

From CES, as told by Kotaku, comes the report that Sony is testing the PSP "as a software remote for networked audio streams." There's no word of when this might actually be released, if it's released, but

It would give users the option of browsing and controlling audio on a laptop steaming to the receiver, all via the PSP.

Sounds like an interesting addition to the handheld's capabilities.
