If you were to add Delta support I would be happy to provide a Mini Kossel Kit:

Hi Tony,
That sounds like an offer I can't refuse! I should have time to work on this near the beginning of November. I'll probably replace the mechanical Z probe by a differential IR sensor.
The work that I can see will be needed so far is:
1. Modify Move code to map the desired XYZ movement to stepper motor movements. In general, the stepper motor movements will not be linear.
2. I need to look at how G28 homing commands are interpreted on a delta. I'm guessing that a command to home X or Y drives all 3 motors up at the same speed, turning each one off as its endstop switch is triggered. Homing Z should not be done until XY is homed, and drives all 3 motors down until the Z probe is triggered. Does that sounds right?
3. Modify axis limit code to allow for the fact that the movement area is not rectangular. Similarly for the M208 command to set axis limits.
What have I missed? [Probably lots!]
