kregg: I was thinking of this also, but if something was going to go wrong with these systems it should have happened already. If there was something toxic given off by the epoxy then it would have affected the fish or coral by now. As far as this stuff lasting, it seems to last forever. I don't think even sitting in water 24/7 will change this material.
Also it is being mixed with sand, so that should give it some protection from the sun/lights. I'm going try this, my only questions are do I go ahead and place it on the floor of the tank directly, or do you place it on something that's removable like you said. Also what color sand? I'm thinking black would be cool, but that's a whole other topic.
