if you are refering to the games/themes/demos and addons here then no. as you still need to have payed for them with your psn account 1st. i doubt there will ever be a way to make content from the above link active on the system the .pkg is installed on you can install them but they won't work.
It's funny to see how people are ungrateful. ifcar0 is one of the people that code nicely and have experience with PS3, so why instead of trolling say simple Thank You for what are doing. Cause there are not that many people to move the PS3 scene.
