what a brilliant idea....
why not make a 404 page on your site with a google adsense search box in it so at least you can get a bit of google revenue for not having your links in complete order.
make it larger than 512 of course and if especially clever preload it with the relevant links
smiley for all that potential extra revenue to be donated by messrs page, brin et al. for having a messy website.
