Shit, first of all, it's not complete. Second, it's Java. Third, it's buggy, and most games with with half the framerate than intended. Even better, some games work under 16 fps. I tried a game that worked with 2 frames /s.
Development on PCSX2 is still coming along, but I'm sure when that's complete they'll put more effort into PCSP. Lewis might hate me here, but I'm more comfortable with software that links back to the computer itself than a platform such as Java. That's it for me.
