I see plenty of info on synchronous rotory gaps, but
I haven't seen much about async gaps.  What are
the advantages and disadvantages of using such a
beast?

It seems that it would have a definate price advantage,
and also make the step to a syncronous setup shorter.
How does it compare to a multiple static gap?
