I use three enabled by default, and up to 6 for difficult queries.

I'm very happy with the daemon approach and I'd be very unhappy with
having to wait for a response for each query individually. I normally
type in queries for 5 - 10 books at a time, and then go back and enter
the returned values. This works very well for me. Of course I'm only
doing at the most 25 books per day, although I would have thought that
someone doing even more books would use a similar method.

I do find that if I haven't had a result back in 2 minutes or so from a
particular query, then it is unlikely that I'm going to get an answer
back at all.

Just my two penn'orth
