Well, normally I'd say that it's too obscure of a word to be worth much, but a Google search shows that the term is used for software, venture capital firms, physics, Linux, computers in general, marketing, etc. That leads me to believe some firm somewhere would want to sopend at least $200 even though it is a .info.
If you catch a group that likes .info, or you hold it long enough for .info to be more well known, I think $800-$1,200 wouldn't be a stretch. Perhaps a lot more, with some luck.
If you limit yourself to genealogy uses you'll talk yourself out of a lot of great potential with the name.
