X2Go is a secure, remote desktop solution that allows you to connect from a Windows, Linux, or Mac OS X into a Linux server. Coupled with Wine (an application used to run Windows software on Linux), X2Go allows you to create a terminal server running Windows applications that all your employees can access. Coupled with Crossover you could go a step further and create various profiles for applications and users.
X2Go also acts as a terminal server, allowing multiple users to connect at the same time while still retaining their own desktop and network resources.
