Perhaps he wanted xword to be able to open a URL directly. I recall that BeCrossword on the Palm had a few sites built in so you could download today's puzzle directly in the program.

But I don't want to duplicate that functionality in xword since that would mean keeping a list of puzzle sites updated. Since you can download a .puz file with the web browser and have it open in xword, all you need is to bookmark those sites that provide .puz files. There really aren't that many out there.
