This Does sound like an interesting idea, and one that you seem to have thought out quite a bit.

"4. Standard clipart license agreement would be included with the Clip-Maps."........There is such a thing? Where can I read up on that? I will google it but if you have a direct reference I would like to see it. Not doubting you at all, just that it is news to me and I would like to know more about it.....as to NOT step on toes that I didn't know were there...

I wish you luck with this new venture, and you are right about the sets. I think that would be one of the major selling point.

Another thought was do you think there may be problems with different publishers using the same Clip-Map in their publications?
