Hacking The Bush IBX100 Internet Set-Top Box?

Matt asks: "I saw the Bush IBX100 set-top box the other day and have been searching the net for more information about it. At approximately £80 it would seem very hackable (i.e. upgrade to Ethernet and add in a larger hard drive). It would make an excellent 'consumer' device for those of us using PAL TV systems, perhaps, much like the devices from the previous Slashdot stories: 'Embedded Linux Box' and '50-Dollar Hackable Websurfer'. Has anybody seen inside an IBX100 yet? The fact that the built-in browser is Netscape strongly suggests it's already running Linux/BSD, but what else is inside?"
