The way I've seen it done in Express.js (or its URLRouter middleware maybe,
I'm not quite sure where it is now) is like this:
app.get('/users/:id(\d+)', function(req, res, id) { ... });
app.get('/users/:name', function(req, res, username) { ... });
You can just put any regular expression in parenthesis in your route for
how that token can be matched. Also allows for regular expressions to
match ".*" to include slashes, etc. You could probably even use
Express's urlrouter/lib/utils.js to build the RegExps for you if you want
to save some work =).
As for multiple URLs serving the same data, we have found it very useful to
use the <link rel="cannonical" href="cannonical_url_here"> tag in our
document head, not for any hand-wavy "SEO" reasons, but for the very
tangible reason of when we (or users) do a Google search for something in
one of our pages, there is only a single valid result instead of two nearly
identical results with different URLs.
