Would be realy cool if oneday it would be possible to tell Kodi just: "Kodi, play me some Jazz" by entering the door, and Kodi starts to play Jazz.

You could of course tinker with that idea even further. Some sort of "presence detection" (your smartphone connects to your wifi, you have a smart-tag on your key-chain or something similar and your house network knows, that you've entered your home), some sort of cross-referencing with the local weather (it's sunny outside, it's rainy outside) and Kodi playing the appropriate music / smart playlist in the appropriate volume.
