Knowing Search Engine Robots' Names - Beneficial to SEO's?

I was thinking about creating separate optimized webpages for each search engine robot to crawl. Creating meta tags to direct each robot to only pages that are specially optimized for that bot seems like it can be a very benificial optimization technique.

Then I wondered if it's worth researching each search engine's algorithm and creating pages specially created for each of their robots. Not to mention that some of these engines probably don't get the traffic worth aiming for.

Seems like a lot of work... (or maybe not)

Does anyone know how else a SEO can benefit from knowing each robot's names?

Here's a nice list of the Search Engine Robots from Search Engine Dictionary.
