Currently, the SCP Plugin only uses the host name as the "siteName" identifier. This prevents setting two different SCP connections to the same machine (the first instance of a hostname in the connection list is always chosen). This would be useful, for example, if two different projects want to archive artifacts on a shared server, but in different locations - or using a different username. A simple patch is attached (against r33992) that expands the site name to:

USER@hostname:root_path

This allows multiple connections to the same server using either different usernames or different root paths.
