UCM has the notion of project name and stream name, with this 2 I think we can makethe viewname/viewstorename unique${user.name}${short-host-hame}${project-name}-${stream-name}.project-name and stream-name should be part of URL.You can do the same for base SCM, by make up you own project name ( dont need the stream name)
I don't think base SCM has a project name I can use...
