Good way to put it. If they expect that keyword to be elsewhere on the site, but isn't... they'll use 'meta keyword' to confirm and give it weight. Especially since it was part of the domain and not a popular phrase.
I find it interesting that you chose not to mention your domain name in the title of your home page as well!
I didn't solely because it's not a popular term, and obviously without the space, very few would search for it like that. But I do have it on other parts of the site WITH the space.
example : if my domain was dogcat.com , I put dogcat as the meta keyword. (without the space)
