I'll take a pic of how I do it to show how the wireless could work (even though I use a wire). If the wireless is RF it'll be fine any where the flash goes. If it's IR or triggered from the flash you'll have to have the sensor exposed, which is still pretty easy.
Thanks Levi for the info-
I'll give it a try and see what kind of results I can come up with---I got afew fish shipping boxes laying around I'll try....
