While I believe your contribution is an interesting one I recommend to not assume too much. We got 2 cats from the animal shelter, and they are not very playful (relatively speaking). They're generally afraid, tho much less nowadays.
What we do is we feed them manually, once a day, the very same amount (using the same bowl as scoop) in the evening before we go to bed (he's on a diet for FLUTD, and she has to eat the same food so she's slightly obese). This gives us the advantage that the cats are not annoying during night, and if they eat too much they'll have to wait till the evening (which means we either get annoyed during day time, or we don't notice since we're not around). We also give them fresh water at the same time.
A major issue is when we're gone for more than a day. But a cat feed machine wouldn't be adequate. Cats need fresh water as well, and enough. Refilling when it is empty isn't enough. Algae are being formed. So this requires manual labour, daily.
