Just to follow up... is there a specific reason why you need to test the application through a remote connection? It seems that, regardless of whether or not the user is sitting at the workstation wouldn't make any difference on the functionality of the application unless there's an architectural piece that I'm not aware of. In the absence of the architectural requirement to test through remote connection, I think that such a test case operated in automation would be an unnecessary test case.
Just my $0.02
