First PlayStation 3 Custom Firmware Created
Stoobalou writes "Hot on the heels of the discovery of the the PlayStation 3 private root key, and its subsequent leakage by iPhone hacker Geohot, the first custom firmware for the formerly impenetrable console has been released. A code wrangler known only as Kakaroto reckons he has created the world's first custom firmware for the popular console — although if you're expecting it to help you play pirated games, you might be a little disappointed."
There are hundreds of options for hardware better at doing the things you just listed that are cheaper than a Playstation.
A $50 router and OpenWRT can do all of that.
