Let me back up for a minute: All that stuff about URL formats is
assuming that the format of the URL, whether it looks "static" or
"dynamic", really is important to whether or not real search engines
out there index the content.
Some posts above imply that, at least for Google, that may not
actually be true, or may only be partially true.
Whatever else, other than the URL format, impacts whether or not
Google indexes stuff (like the server maybe falling over under massive
Googlebot load), is at least (probably more) important than the URL
format issue itself.
But if it's likely that the URL will always be at least a piece of the
puzzle, it would be very nice to have a tool to present whatever URL
format we want, and that's worth discussing.
