The PS3 scene is getting extremely interesting now. Can wait to check out their documentation, hopefully where close to creating our dongle for less than half the price which is awesome.
It will require some sort of hardware be it a home made dongle or a PSP or an android phone or a pc but you still require that device to emulate the handshake with the PS3 which is the closest to free option. It CANNOT be put on a normal usb as its not compatible.
I think the PSP will be used to emulate the jailbreak. It is poetic justice - Sony's most hacked console is being used to hack their least-hacked console! also bear in mind, Mathieulh (and presumably the rest of the team) are of the PSP scene, so it is logical to assume the PSP will be used in the hack.
Actually quite nice for Sony as well... perhaps major boost in psp sales
@ Jes03 Don't think they can disable the USBs as a lot of their devices use the USB slots such as PS Move, PS Eye Toy, Play TV however they could implement a security system that only allows verified devices and block off black listed ids and unsupported devices.
I would like to see the PSP be used to emulate Jailbreak its lying there doing nothing after installing lots of homebrew and hacking the living daylights out of it. I could see a package coming out that you run on the PSP that sends the files over to the PS3 after pressing the power and eject button exactly like the Jailbreak itself.
