Keyboard Case for PSP

We're expecing a PSP 1st party keyboard sometime soon. Actually, PSP needed a keyboard eversince the 2.0 firmware update with the browser but somehow it never happened. Anyhow, I am sure the one Sony making will worth the wait. Since I've been programmed with a 3rd party mentality and a big fan of multipurpose peripherals; I'd have made a soft keyboard for PSP sewn inside a protective case.
