Having two PS3's

[Sylin]

FYI - I did do a search for this, but the results page kept telling me either the word "two" "2" or "ps3" were too short or too common and thus displayed everything.

Anyhow, I'm debating picking up a 40gb PS3 for another room in our home. We currently have an 80gb in our living room.

Can anyone with experience shed some light on how to set up the 2nd PS3 without causing interference with the 1st one? (ie. controllers from PS3a keep turning on or affecting gameplay on PS3b) They will be in 2 different rooms, but they are literally on opposite walls from one another.

Or is this not a problem because the PS3 is bluetooth and thus the controllers will only mate with the PS3 they are configured for?
