cso compressor for android?

[TkSilver]

You can use a USB on the go cable to hook an android phone\tablet with otg compatibility directly to a PSP with CFW to rip a UMD directly. I am assuming the android device in almost every case would be faster to compress an iso to cso then the psp itself would.

So there is a legit scenario that I have personally used before, but odds are the most common use case would be piracy related.
