Where are you getting that OVT figure? I see just over 1 million when I look...
Anyhow, its a very nice keyword name. .nu is a minor extension, although the word /nu does mean 'now' in some scandinavian countries I believe (don't crucify me if I am wrong, my grasp of foreign languages has been leaving me rapidly since leaving school!). I beleive Sweden is one country that understands this meaning, so it may be best to develop or market to this area.
I don't know of any massive sales in this extension, although I have myself paid mid $xxx for a name with a .nu ending (loans).
I would value this name somewhere around mid-high $xxx reseller, maybe more if marketed well. The problem wih this sort of name is that there aren't so many domainers dealing in the more obscure extensions, so reseller sales are harder than with a .com or better known cctld. If you are in a rush to sell, you may find even low $xxx hard work, but with time/marketing $xxxx is very acheiveable.
Oh, and if you find a serious .nu investor, let me know! :hehe:
