Maybe some others around here might find that interesting as well:
You can unlock the bonus features from connecting the PS3 version of AC3 and "Liberation" on Vita even if the region of the games doesn't match the region of the PSN account currently in use!
I've just bought the european versions of both games, and unlocked the extras while being logged in on my main american PSN account on both consoles.
It seems that the games only check if the same account is used on both consoles, and then unlock the bonus features without accessing the PSN store at all.
