Actually, whenever you represent the & character in HTML 4.0, you should write & even if it is in the middle of a CGI URL. This does not change the URL, only its representation in the HTML document.
If these are the problems we're facing with incorrect HTML, there's no need to be scared... :)
It is not very difficult to do HTML 4.0 correctly. The change to XHTML is a much bigger step (and unnecessary, if you ask me).
