I don't think it's worth anything more than reg fee. The name should be dnaavenue.net to make sense...i looked at first and thought dna venue.net lol. Which gives a totally different meaning to the name, plus it's undeveloped and a .net.
If you develop it, it could sell well. DNavenue as you said would be good name for a DN forum place but as it stands i dont think it would be worth too much - someone might you pay around $25-$50 if you find the right person
