Anyone used this method? Pro's, con's?

I had a nichrome wire in a spiral pattern at the back of my newt once and as soon as I switched it on I'd see the focus go off in realtime so I dropped that idea real quick. A fan at the back of the mirror seems to be a sensible idea. A long dewshield goes a long way keeping the moist from falling into the tube too so you keep your secondary relatively dry.
