Gaming LittleBigPlanet PSP saves

[Kanahpoo]

Just bought a PSP this weekend and i have a question:
Seeing that the PSP (unlike the PS3) only has one user account and some games (like LittleBigPlanet) uses only one (auto)savefile, it's kinda annoying if multiple users want to play the game. So i was wondering can anyone confirm using multiple MemorySticks is an option to resolve that limitation of having only one savegame for LittleBigPlanet?
I don't think creating multiple PSN accounts will resolve this issue cause this is only used to go online and has nothing to do with profiles on the PSP itself, right?

If you have the UMD then sure, it'll work.

If you're downloading it, you'll need to have the game on both memory sticks.

I'm using the UMD, so i guess i'm good.
I read somewhere that the LBP save files are restricted to the user who created it, but seeing that in this case both savegames will be created by the same user it'll work just fine? So only sharing savegames between different users won't work? The PSP won't go all weird on that?
