I just bought an E3D V6 today, and while I was on the E3D web page I saw a couple of neat upgrades. One was the "Kraken" 4-nozzle setup, and the other was the "Cyclops", a single nozzle with two Bowden filament inputs. A bit beyond my means right now, but I am wondering: what electronics would I have to swap out for my Melzi in order to drive two or more extruders? RAMPS? Or something else?

Wow - with those prices I would DEFINITELY have to make it a "one of these years" modification!
Now, I'm running a Panelolu2 on my Melzi. Could I possibly run a second extruder off one of the MOSFETs on the Melzi adapter for the Panelolu2? How would I have to adapt the firmware, if so? That would at least allow me to run a Cyclops without changing the electronics.

You need another stepper drive and a thermistor as well as a MOSFET. There isn't enough I/O unless you remove the P2. Then you could connect a Pololu style stepper driver, a MOSFET and a thermistor circuit to the expansion port.
