SSL-Explorer is the world's first open-source, browser-based SSL VPN solution. This unique remote access solution provides users and businesses alike with a means of securely accessing network resources from outside the network perimeter using only a standard web browser.While the tool looks great, their self definition is not completely correct.

2. you can register for a full featured VMware appliance running in enterprise mode here.
