I've put together a VMware virtual machine configured with Debian Linux and a Hobbit server installation. If you have the VMware Player installed (free download from www.vmware.com), this lets you have a demonstration / test / play-around-with-stuff Hobbit server running without setting up a dedicated server for it.
Since VMware Player is available for MS-Windows, it will even let you run a Hobbit server on a Windows-based system, although at the cost of having a virtual server running (i.e. you'll need a bit of RAM to support it).
For those who want to play with it, it is available from the Hobbitmon "Files" area on sourceforge.net. Choose the "hobbitdemo" package: http://sourceforge.net/project/showfiles.php?group_id=128058&package_id=2001...
Just one warning: It's a 250 MB download.
