Could be useful for an expired domains type service. I once saw some really useful software which ran in the browser background checking whois records of visited sites, and informing you if they were due to expire soon. The name of that software fails me, but that might be because they didn't have your domain...
I would say in terms of pure domain value, about $30 , but maybe approach some relevant software developers and you could get some more. I expect there are lots of similar names about though, so don't go above $100
