I've been intrigued by The Strobist's blog and all of the multiple off-camera flash setups.
Unfortunately, trial-and-error isn't the best strategy for film.
I've found the Nikon SU-4 that can be used to trigger off-camera speedlites and still retain TTL metering. I may give that a try.
Anyone else have experience with manual configuration of multiple off-camera flash with film?
