I guess that's why this biz is so interesting to us. I look at sprayers.org, pause on it for a moment, and move on. If I could think of any reasonable resale market for it, I would have grabbed it. If you talk about developing it, that changes things, but you still have to find an interested party. I can't imagine any mature ($$) spraying company such as Campbell Hausfeld being interested in a .org, which leaves you with the possibility of a trade group (no $$) or I suppose a niche porn site (lots of $$)
Either way, it seems like lots of work for little chance of reward. I would pass on it.
