The virtual appliance concept keeps spreading, with over 300 entries in the Virtual Appliance Marketplace. If you have downloaded and used a virtual appliance, we invite you to fill out this survey by December 31 and you will be put into a drawing for one of three iPods. This short survey  helps us know how you are using virtual appliances today and how we can work with application and appliance vendors to make them better. Fill out the survey today. Thanks!
