jclouds-plugin v2.8 provides support for copying slave.jar to a provisioned instance in a *nix style environment. If the SSHd environment is on a Windows slave and is using the command prompt or powershell environment, /tmp is not able to scp and execute the slave.jar file since /tmp is a valid path.

Adding a mechanism to indicate that the JCloud template is a Windows slave would allow for a different copy and execution path for the slave.jar.
