Kind of silly I suppose, but I was just wondering:

1. Does code allow soldering for residential wiring where you live?
2. Where do you live?

Please, I'm not trying to start a debate over the science/physics/howto's of
soldering or its relative pros/cons.

Can't answer the question (a good one, by the way), but it brings up
another, even more interesting, question in my mind: assuming it is
legal (I'd suspect it is), what about insulation for the joint? Is
electrician's tape sufficient?

Use several layers and keep the tape under just enough tension to
stretch and mold itself to the joint. Only things better would be
spaghetti tubing or heat shrink.
