GEO:IP And Search Engine Optimization Question

Just wondered if anyone knew if it was possible to target specific keywords that appear in a web page based on the location of the surfer utilizing a search engine?

For example, lets say we have a surfer using Google who lives in Miami, what im hoping it is possible to do is something like this in the Meta Tag section of the html code...

{title}Find Toy Stores In [ip location]}
{meta name="Description" Content="[ip location] Area Online Toy Stores"}
{meta name="Keywords" Content="Childrens Toy Shopping [ip location]"}

So that when the surfer sees the search results for the term 'Toys Stores' for example, the SERPs displays 'Find Toy Stores In Miami' for the link name.

Does that make sense and, if so, does anyone know if it is possible to do?

Regards,

Well I know you can serve specific banners depending on the geo region of the IP so i'd assume you could tweak it to put it in a title tag... but that is just a guess, from a non techie bonehead..
