It is interesting and small but you still need a microcontroller, at least, for switches... But I think it can be done with that FTDI... 6 outputs for step+dir (three steppers) and 2 inputs for limit min/max. Yes, it can be an interesting solution.
Here is the one for 18F4550: http://www.cncdudez.co.uk/ Free hardware+firmware and free PC software.
