However, my concerns over execution, especially after looking at the website, probably put it into the gimmicky category. I would have to test it out, see if I like the software interface, and figure out a good way to set it up so it doesn’t look tacky.

Overall, I’d say the concept could have promise, even for more mainstream couples if it was done well. That is a huge ‘if’. When a guest walks up, the interface can’t be cheesy or clunky. As for decorating and presenting the hardware, it looks like they need to hire someone with a little more style to help them design it. In other words, there’s room for competition to come along and improve it.
