It depends on the engine you are talking about.

In someways, we cloak here to simply give the spider, data intended for the spider (bots tags that would otherwise eat alot of bandwidth). However, I'm pretty sure that this thread wasn't interested in benign cloaking.

There is also to consider the new engines such as MSN and a couple of those in europe that still use on-the-page factors. In those cases, cloaking can go a long way to protecting your proprietary work.
