Is it possible to login to ITeamRepository using an existing stored alias?

public static ITeamRepository login(final String rtcuser,final String rtcpasswd,String repoURL)
			throws TeamRepositoryException {
	monitor = new SysoutProgressMonitor();
	ITeamRepository repository = TeamPlatform.getTeamRepositoryService()
			.getTeamRepository(repoURL);
	repository.registerLoginHandler(new ITeamRepository.ILoginHandler() {
		public ILoginInfo challenge(ITeamRepository repository) {
			return new ILoginInfo() {
				public String getUserId() {
					return rtcuser;
				}
				public String getPassword() {
					return rtcpasswd;
				}
		};
	}
	});
	monitor.subTask("Contacting " + repository.getRepositoryURI() + "...");
		repository.login(monitor);
		monitor.subTask("Connected.");
		return repository;
	}
	

Does anyone have an example of using an existing client alias to obtain a connection?  I am writing a script now where I do some things through lscm (commandline) and other things through a custom library.  I would like to use the stored alias so that I don't need to collect the login credentials from the user.  ITeamRepository.addAliasRepositoryURI seems like it may be referring to a file URI but I'm not sure if that's true, or if it is, how I would use it.

Any ideas?
