Addonics has a product called a USB to NAS Adapter. This will allow a usb hardrive to appear on a network. no if we can find a small small small ehternet wireless acces point, tear down the usb adapter, and load linux on it we will have an internal nethostfs server inside our psp's connect a 2.5 hdd to the usb port on the NAS device and we have an internal psp hardrive. FYI the usb-nas device is 50 $ 35 on ebay!
