A developer has created a package that will allow use of the Sony Remote Play Software for the PS3 on any PC (i.e. a non-Vaio system). More info here: http://www.sonyinsider.com/2010/06/18/remote-play-software-with-ps3/
Setup instructions are included in the zip file- along with a download link for the Remote Play Software: http://tinyurl.com/sonyvrp
You will need to pair your system with the PS3- so you will need to have access to the PS3 to initially set this up.
