[Leica] camera release limiter?? weird question/ need

[faneuil at gmail.com (Eric Korenman)]

Not sure where to ask this -- but thought my LUG pals might help:

I have been setting up 'photo booth' style shoots at parties.
I let people take their own pictures with a handheld trigger wired to
a pocket wizard.
Sometimes I give them the pocket wizard directly. (everything covered
in gaffers tape, except the button)

The results are wonderful and very well received.

Only slight issue: people (esp after couple stiff drinks) love to hit
that button as fast as they can.
It is ok, but strobes often can't recycle fast enough and I end up
with way too many shots.

I'd love to wire in some circuit that allows, say, only up to 1 shot per 
second.
I using a canon 5d, and I don't know of any on-camera setting that
would accomplish this.
Any solder gun types out there who have solutions?

thanks,
Eric
