I may be speaking out of turn, since I have no special expertise with either club owners or club lighting, but you might try taking it to the channel to market. If you can find club lighting supply houses (which I am only guessing exist) -- and allow them to make hearty margins, they'll push your software for you as part of their new installs / sales. Again though, I don't know the market or niche, so take this sugge…
It's not a bad idea. At the consumerish end of the market, people often buy club lighting from Guitar Center[0], which sells a large selection of generally low-end to midrange DJ and club equipment. An aggressively-priced low-end version could sell very well there. The higher end of the market is served by specialized lighting dealers. Professional lighting equipment is very expensive, such that prices are not usuall…
I think if you could get them to push for you, and maybe MusiciansFriend.com (a similarly sized competitor, a la New Egg vs. Tiger Direct), you'd be in decent shape, distributor-wise.
Either way, best of luck. Let us know how it goes.
