Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
If you're referring to the PS3 you can buy an item for @$20 that'll allow you to control your PS3 w/the Harmony remote.
Unfortunately, you can't turn the PS3 on using that $20 IR adapter. The USB ports aren't powered when the PS3 is off. Ridiculous.
