bird and i have discussed this a while ago and I reckon it will take the form or the active cooling unit on the newts with stepper motors on the collimation screws. these steppers would be driven by reading the diffraction rings and adjusting accordingly.
might be a bit of a pain with sct, as i assume you collimate at the front.
but yes, you could auto guide and collimate based on feedback form the camera image.
Paul Haese over on SCP is also talking of some software to help control all the systems for 18" sdm wilst imaging jupiter.
We will be playing with ideas at the wartnook jupiter camp in june
watch this space over the next 12 months.....
