Short names for Pages

I was wondering about the following: wouldn't it be nicer to base the url for a page on a 'short name' instead of the page's title? I don't like this URL for example: http://prog2.vub.ac.be:9090/declarativemetaprogramming/ When telling people to go take a look at the DMP site I'd prefer to use the URL like http://prog2.vub.ac.be:9090/DMP/, but I don't want to change the page's title to this abbreviation either. So it would be nice if the editor for pages allows you to not only set a 'title' for a page but a 'short name' for it as well (by default: none). The page's url should be derived from this short name. I could probably hack this into Smallwiki myself easily, but it seems like a generally useful feature and I'm wondering about a small issue as well: should the *-syntax for making a link allow you to use short names for pages too? What happens when the short name of one page and the title of another are the same?
