I have a PlayStation 3 and I have 2 demos that I downloaded. My friend wants the demos, but he doesn't have his PS3 connected to the internet so he can't download them. So, can I copy the demos onto a USB pendrive and then put them on his Playstation? Please help!

No SONY do allow that function because it is illegal because somebody could replicate the demo or steal parts of it. They also do this to prevent people from sharing out downloadable content bought from the Playstation Store. You can share this anyway by logging on to the receivers PS3 on your account and look at what you have bought and then re download it. This can only be done to 5 PS3's unless the company that made it has put a lower share limit on
