How to add new search engine options in Safari for Windows? Without resorting to editing the host file (as shown in this Apple.SE thread), is there any way to add a new search engine option to Safari for Windows? Glims works great on OS X, but unfortunately is not an option since my work machine is a Windows 7 box.

EDIT: I'd prefer a generic solution, similar to Glims, that would allow me to add any search engine to the search options.
There are a few Safari Extensions that will enable this:
