i allready have google toolbar :) but i just want to be sure this plugin is not available be4 i go in this issue , i have some idea 2 integrate this into wordpress .
but i think api-key will cause a problem . because using the google api-key you are allowed 2 make 1000 query/day .
except if in the installation procedure of the plugin you ask the user to enter there api-key .
or ... get 5-6 api-key and make a random select of the api key ..
Thank's anyway i ll check this after my exams :)
