The resulting charcoal is as close to bio char as we're going to get. What are the advantages and any disadvantages to spreading this plain old charcoal (just charcoal, not ashes) on our gardens?

In small quantities it's unlikely to do any harm and may well do some good. I'd suggest mixing it with compost when you use that as soil remediation. The damage seems to have been caused when adding large concentrations of biochar in some circumstances. That's unlikely to apply to the kinds of quantities coming out of your stove (although you might want to look at efficiency if you are producing charcoal, not ash).
