There's a few threads in the sell+buy about cloaking. The most popular software package is
shadowMaker. Fantomaster's system is on sale right now for $2,280. Quite a few people have asked me about this software. So I have developed a competing script that has the same featureset.
It comes with daily (automatic) updates for the spider database. The IPs used by Googlebot, Slurp, msnbot, et al change often and must remain 100% up-to-date. If your cloaking package does not remain up-to-date, and the software presents the wrong version of one of your pages (in error) to the spider, it could result in your domain being banned from that SE.
Anyone who is seriously interested, let me know and I'll arrange for a demo. If you have any questions, feel free to contact me. See sig for contact.
