Make RSS feeds from last.fm Shoutbox Pages

I was somewhat interested in seeing what people were saying about the new Boris albums on last.fm, but reloading that page is so 1993.  I wanted to read it through Gwene, but there’s no RSS feeds on last.fm.  So I whipped one up (in Perl!  *sob*) and put the service on Quimby.

Feel free to use it or rewrite the Perl script to be less doubleplusungood.
