Well, without a starting point, there is no way for your spider to find your content. The whole point of hyperlinks is so that there is a way to reach pages from other content.
If you have a page that is never linked from another page, it is very unlikely that your spider will find it. There are a lot of search engines other than the popular google, msn or yahoo.
Think of it this way -- how would you find where your content was posted? If you aren't able to locate it "pragmatically" -- that is, from typing a keyword in a search engine -- then it will be very difficult to write a spider that does the same.
There are other issues with this -- how will prove you hold the copyright to the content?
