Hi Wot,
I think although it is not an expensive name, it could be pretty useful to develop a site. I think type in traffic is irrelevant. Its value lies in how easily clients can remember the name, and the image it has. You idea sounds good. I think it is suited to .org, and maybe people will be more likely to get involved if its not for profit.
Domain value $500, but more if there are few alternative domains for competitors.
