I suppose that will work, though since the user/password URL format is 
not technically allowed for HTTP I expect that it will not work for 
everyone's HTTP libraries and browsers. Internet Explorer doesn't allow 
this since Windows XP Service Pack 2, I believe.

I would be concerned that some consumers would be unable to accept such 
URLs, and even once they have the links they generate will be unusable 
for many web browsers.
