Sony's CES booth holds promise for the wi-fi connected multimedia hound: a PSP that acts as a software remote for networked audio streams. While experimental and not yet confirmed for release, the software looks cool.

The PSP basically acts as a cheaper software remote for your Sony brand AV receiver. It would give users the option of browsing and controlling audio on a laptop steaming to the receiver, all via the PSP. The receiver unit on the show floor was, I believe, the STR-DA6400ES — one of the pricier home theater options Sony offers.

Currently, the interface follows the Xross Media Bar standard used in recent Sony products and, while it could use some massaging, it works.

No word on when or if Sony plans to release this little software perk to the public, but we'd guess expressing your interest in getting your hands on something like this wouldn't hurt.
