There are many many servers that run on the slug. I am serving to a Showcenter 200, and I use wizd. (Although its only one of many alternatives. http://swisscenter.co.uk http://www.oxyl.de just to name a few)
Wizd also allows me to serve big files (>2GB) without a hitch. And the slugs performance is decent enough to allow HDTV stuff.
