Yeah, but she doesn't want all the buttons from all the remotes moved to a single monstermote, she wants the TV remote to do everything as if the only thing connected was a TV.
"Why do I have to choose channels on my TV AND cable/satellite box?" and "why are there multiple sound levels for the HiFi, TV, cable and DVD boxes?" are questions no one has adequately answered and they're questions everyone except geeks and techno-fetishists are asking.
I actually want Apple to do something about this, though I'm not normally in on Apple's philosophy. I propose the following:
1. Any TV channel without content on it goes away. If you only have 3 channels with signal you get no benefit from being able to select 96 channels of white noise.
2. Cable/satellite channels stack on top of the TV channels. It just looks like your TV has more over-the-air channels when you plug in the box.
3. DVD-players and so on are treated as channels (see 3). EXT goes away. A device can be represented by as many channels as it wants, but they're all stacked on top of the TV channels. No special treatment, except perhaps a lower number. A device is turned on when you select a channel associated with it.
4. Any sound systems automatically defer to the settings on the TV. They behave as if they were the TV speakers. No setup. No settings. No knobs to turn. Plug and Play. If a sound system has buttons it's too complicated.
5. DVD/BR players lose all but play/pause, ff/rwd and the nevigational buttons. Why is there a numpad on my DVD remote? I don't even want to know. Just make it go away. Same with the TV remote itself: Everything except on/off, numpad and volume disappears. Remotes are not unified, but everything that can be deferred to the TV remote is deferred to it.
The above isn't completely perfect, but it's kind of obvious.
I'm currently studying but I might be available for hiring or consulting. I obviously compare favorably with whoever is maintaining the status quo.
