If they could make multiplayer work fine in PSP2 (it was fine when I played with a couple other friends, but I haven't put a lot of hours into that game like I have with other PS titles) then I don't think their next attempt will be so bad even if it incorporates cross-platform.
There's probably going to be some quality control enforcement (since prowler says that 3G won't be allowed as a connection for the game, I think they will have to find a way to defeat cell phone tethering too. Or, at least make unstable connections a known status (like an icon or a ping time indicator visible to all -- FFXI used icons to represent disconnection next to player names when they dropped link) to players who group with them.
