I wrote about this 13 years ago during the Les Kelly vs. Arriba Soft Corp. court case(s):

I went the other way, though - my thought experiment was, what if you came up with a standard way to "say" a URL in plain english. As in, just a wordy, colloquial way to describe the content that is in a URL.
Obviously this would fall under free speech and nobody would consider barring such speech ...
So I think now, as I did then, that if you really want to demonstrate the ridiculous nature of these proposals, you need a browser plug-in that allows you to describe URLs in plain english and then demonstrate that to the court (or whomever).
