It sounds like quite the mine field you are embarking on Bradley. I guess it depends on the industry. Some industry directories take exception to their listings being used and are very diligent in seeking out copies. There are a number of spiders that do nothing but search these out.

IMHO the best way to build a directory is to seek out the sites by spider or the old fashioned way (Surf) and add them, not as quick but less frought with potential hostility. Webmasters IMO will respond better to an e-mail letting them know they've been added vs. inviting them to add their site, unless the note looks fairly personal, like you actually visited their site or you can demonstrate the value to them of adding themselves to your directory.
