PSVita supports multiple PSN Accounts per system, but only if you have multiple memory cards.

Why do you need multiple accounts? I just don't get it.

To share with family members or roommates. 

Why can't you share with only one?

Well typically why I never share and will never, is because I never want anyone touching my files. I was just answered your question. 

So then you're not really sharing, are you? I'm impressed.
