Since we need only about 5-10 seconds of smoke (Skywriting isn't really on the menu) could we just drown a glo-plug in a small tank of 'fog-fluid' (glycol/water) and control it with a relay? (This probably needs a less expl--um--messy design cycle...)
Here is nice overview of smoke generating technology... (On a *different* wiki) http://en.wikipedia.org/wiki/Theatrical_smoke_and_fog (Yes, yet another excuse to play with LN_2) Typical(?)
