Gameshare On Ps3

[ayabrea38]

I know the rules say you can share the games that you have downloaded from the Sony store but I remember something about the amount of times you can do it changing from five times to twice.Does anyone know what the legal amount of times is,and can they back this up with a link or something?
I am not trying to get out of buying games exactly,but I have a game,downloaded recently that both my son and daughter want on their own machines(don't even think of asking them to share-please ;) )and I know Sony allow it,just how many times.I cannot find an up to date answer so far on the internet,or from Sony themselves and don't want to get any of us into bother-the Sony police are everywhere!!
Any answers that can be backed up,or point me in the right direction would be great,I only want them backed up cos OH worries about stuff going wrong,and lets face it,with our track record generally if it can go wrong-it will!
Much thanks
Aya
