I didn't forget the PSP, I said home consoles.
I believe the homebrew issue with the PSP is that enabling homebrew also enables piracy. On the PS, PS2, and PS3 they were seperate issues. (ie. a Net Yaroze didn't allow you to play CD-R copies, just as the PS2 and PS3 Linux don't allow you to.) Also remember, the 1.0 PSP didn't have ANY protection.
