PS3 USB Jailbreak

No mind blowing feature that i could point out as they are all just as the same with the others, but one thing in particular that seems to be interesting. “Can be removed once started. No need to have the USB key always into your PS3!”
Is it already doable with other clones? I mean i didn’t own one since i borrowed an iPhone to Jailbreak mine. So, would like to know if the feature is already implemented even on a board running PSGroove with Payloads. For a full list of features take a look here:

·Fully updatable via USB on your PC using an encrypted bootloader.
·USB Plug and Play solution that installs in seconds without any need to open up the PS3.
·Supports any available type of firmware for the PS3. Psgroove, PSfree, and so on.
·Can load directly PSGROOVE .hex files and Payloads .BIN files
·Can be removed once started. No need to have the USB key always into your PS3!
·Does not break your warranty seal.
·Compatible with all PS3 models, both Fat and Slim.
