1-5 Clicks for guests & free pass for bots



I just saw this addon: http://xenforo.com/community/resources/first-click-free-smart-content-hiding.1132/

As I get no response there, I would like to ask if anybody could program an addon like in the link but with a support for all search engine bots, not only google.

The next thing would be an option to set a specific click rate a guest can do before they are reffered to the sign-up window. For example I choose 5 clicks for guests in admincp and everybody except search engine bots, will see the sign-up form after they did 5 clicks.

Any chance to get anything like that? :)
