So, if all your Tivo's are going to start playing mp3's and photos, aren't they ascending to the level of general purpose computer (sans office products)? If so, can we hardware hacks not just create our own Tivo's? What's the proprietary component(s) of a Tivo that make it so unique? And could those components be dupilcated or emulated in a standard beige-box PC that we build ourselves?

'Cause hell, if we could build it, we could do whatever we wanted with it. Ethernet, USB, MP3, photos, Linux, WebTV (hahaha). Anything.
