Having never reg'd a dot.name, nor even really studied them, take everything I'm saying with a grain of salt;
The connotation to 'Overture' is rock-solid of course, that's even what I thought this was when I read the thread title... I expected to see some name with high overture results, ha. So of course a dn like this would be great for developing along the lines of doing anything overture does.
I actually thought it was an unusually nifty use of the .name extension, and kudos for the brainstorm. With any other extension, I doubt the Overture owners themselves would be interested in buying an 'OVT'... but with this ext, if I had Overture I'd think this was ideal!
Also, doing a quick SE search shows a nice variety of end users with the acronym OVT, and that .name ext is so appropriate and applicable, for a lot of uses, I think you have a very strong dn here.
To me, it's a wild card: of course, the weaker the extension the lesser the value... and yet, OVT with .name on the end, to me, is so nifty and usable that it would seem to be an exception to that rule and might be attractive to a variety of end users, enough to be worth more than similar LLL.name's...
Sorry that I don't know enough about dot.name to give any value. If I had to gut-feel it blindly, I'd probably tag a high xxx to low x,xxx sticker on it just because I think it flies outside the box in a very clever and attractive way...
But I may be wildly off in my pricing, in either direction, so I hope someone else here can give you more accuracy.
Nice thinking.
