There is an article on Slashdot about VMWare releasing a free "VM Player" that lets you use VM images created with one of their other products (Workstation, ESX, GSX) on any machine running the player. One of the downloadable examples is a VM image providing basic communication tools (Firefox, Thunderbird, Gaim, etc.) that effectively keeps those services inside a sandbox. The player is available at http://www.vmware.com/products/player/ but the site is pretty slow this morning. --rick
