Just thinking again about the HTML 5 Opera features available and an abandoned HME UI-replacement project I was thinking about long ago (abandoned because it couldn't include closed captioning). It seems like it might be possible to do it with Opera (I believe that has all the CC support built-in), but the TiVo remote's teleport keys (TiVo, LiveTV, Guide) would also break the "immersion." So I was thinking how the RF remotes could maybe be paired with an Arduino or Raspberry Pi instead of a TiVo, then that device could use the TiVo's network remote interface to forward all the commands except the teleport keys (maybe sending different commands that could be intercepted to do an immersive equivalent). More generally it could be useful to convert a TiVo Remote to do whatever. I've never built any of these things, but if there is a kit that has the required RF features it might be an interesting project to get into. I'm guessing nobody has done this before so there isn't an existing TiVo-pairing/interpreting library for one of those devices, but if one exists that sure would be nice. Anybody have any useful thoughts on this?
