1) I am afraid, you will not be able to use the Virtual Learning Environment (VLE) for this purpose because of the reason you mention.

Your vCampus subscription includes a development system. Please see General vCampus FAQ for details. It's recommended to create a Machine Specific license file through vCampus Download Center -> Link to MLA. Please note that this license expires at subscription end. When you renew your subscription you will have to create a new license activation through MLA.
When you install the Coresight client application for iPhone or iPad, it installs with demo access to one of our servers already configured.
