How To Get One PSN Account On Two Separate PS3s in My House?

[krinkle]

Maybe some of you guys that are more into the gaming side can help me out on this. I have mainly been more of a movie buff but am getting back into gaming more too.

I have two PS3s, one is in the theater and the other is in the living room.

The one in the theater has been online 24/7 since I bought it. It is my "bat cave" where I go to watch movies and play games on 160" big screen. This PS3 in the theater has my active PSN identity and all my save games and PSN online store information.

The one in the living room has only gone online a couple times for firmware updates. I have never played games on it, and it has only been used for movies.

I have started gaming more and want to have my exact same PSN account and exact same save games on both PS3s so that I can play games on either one depending on where I am in the house.

So here is the question:

Is there any way to get all of my PSN account/Save games exactlty the same on both PS3s?

Many thanks in advance.
