Returning a link that expires in an email to the requester is a method that works nicely. It does require some programming and maintenance, but would be a nice gatekeeper.
Rather than this, I support the idea of an image with letters and digits in various fonts or colors (so they cannot be readily harvested by OCR methods) that are to be manually copied to a text entry field. I've no idea of the relative amounts of effort required by these different approaches, but I suspect that such images are readily available on the Web and a sufficiently large collection could be used with each presentation being arbitrary. Perhaps once this is done -- and hidden from page source view -- it would not need much maintenance.
