Houston, just a thought but I did do the uplit skirting last year and finally dropped it. My opinion, it just didn't enhance the overall look, it cheapened it. I don't think the lights will make the tripods any more noticeable either than say, black skirting, which is what I use now. I know there are guys here who hate that "tent" look but the feedback I've gotten from planners and brides say that they appreciate the effort and like it much better than bare, metal poles (several have commented to me about it). Now as for tripping hazard, the best way to do this is by placement. Anytime I place my t-bar up around the table, it becomes a hazard and I've seen several guests stumble on it. Personally, I find it's best to put the stand somewhere behind my table, preferably off to the side. I still skirt it with black material, to hide the poles, but I'm using placement to prevent guests tripping over it.
I'm actually glad to see you delving into this area. Personally, I think the guys who are sticking with the "audio only" thing are just being stubborn and dinosaurs. You've got to change with the industry and kudos to you for continuing to work to improve what you're doing. Hope this helps.
