For over a year I've been trying to get my PSP to talk to my PS3 over the internet. Today I cracked it.
There have been problems with routers and methods. It all worked today and the picture above shows me listening to my music from 30 miles away. The stream is a little choppy but not that bad considering the distance it has to travel. I'm going to try a few experiments and see what else can be achieved over the wireless connection.
For now though I'm very happy.
