On the "adjusting them as you type" front, the Wooting keyboards already support detecting a key retrigger even without a full release. They are monitoring key position and if you start to release and then push again they can make it trigger a new keypress. I agree that having a software defined key-press resistance would be amazing. If you could manage that and then add in haptic feedback to simulate standard mechanical keyboard actuation clicks...
