"One-CLick Multi-Site search" script in new scripts section

[admin]

This script searches using the search engine selected for the search term entered. My questions is: Can this script be made to search all of the sites at once rather than selecting each site spearately for each search. By that, I mean simply entering the search term, then clicking submit, and then the script searches all of the search engines defined in the script at the same time and returns a list of compiled results. Is this something that can be accomplished, or am I trying to do something impossible?

Thanks!
