Herb and others, I thank you for your interest. The work that calls for the remote shutter trigger is a portrait project involving dog agility. These are posed portraits in the sense that the agility exercises are not within a formal test or competition, but are done in an agility studio with artificial light. Below or examples of images where the shutter remote would be very helpful. Five lights (Canon 580ex II speed lights) are in use, each associated with its own modifier. Triggering is done by the Odin system. Because I prefer the appearance of the portrait at f4.5 or so, and because these consumer flashes really don't really offer a short enough flash duration to freeze the dog's motion when they're close to full power, the camera focus has to be pretty accurate. I'm pre-focusing, and not allowing focus during the actual shot.
Where the remote comes in is that I'm having a hard time judging the perfect shutter instant when I'm viewing the dogs' jumps from the camera location. What I'd like is to be be alongside the physical jump rather than with the camera, judging the dog's trajectory, and releasing the shutter from that vantage point. Most of the shots are at either 135mm or 200mm, so I need to be some 20-35 feet from the camera location - hence the wireless request.

I elected to go with the PocketWizard III transceivers for the shutter release. Since some number of my collaborators use the PocketWizard system, that felt like the most practical solution. I believe there will be no conflict between the Odin system and the PW, as the radio channels won't overlap, and the PW shutter trigger occupies neither the camera's USB port nor hotshoe.
I wish there was a PocketWizard system that allowed control of light output within zone, like the Odin system does offer, as the whole system could then be done with PocketWizards, instead of the hybrid I'm going to be trying here. But I suspect the bulky nature will be workable. I promise to report what I find, in terms of Odin-PW compatibility, in the next week or so.
Many thanks to all,

Ah! First (Paul), nice to know the 602's do wake the camera in shutter mode.
Second - and not to throw a wrench into things - well yes, throw a wrench into things.
Would something like this laser trip system work? http://www.gadgetinfinity.com/cactus-laser-trigger-lv5.html
This absolutely looks like what it was designed for. I remember reading about it some time back and wondering what I could possibly use it for!
[edit] here's an explanation of how it works: http://flashhavoc.com/cactus-lv5-laser-trip-trigger-now-available/
There is also the trap focus on the magiclantern software, but that wouldn't work with your camera. And I totally forgot - cactus makes completely straightforward RF shutter release systems - so check at that link - that could be the simplest solution.
