Url progress with ASP.NET

I’m much too busy to be blog reading…but here I am anyway, catching up on a few of Jon Udell’s latest posts.  I was happy to see ".aspx considered harmful", which discusses why Urls should be minimal in order to be future proofed and to have the appropriate style/brand.  He links to Scott Guthrie’s October post about ASP.NET MVC Framework which "includes a very powerful URL mapping component that enables you to build applications with clean URLs".
