You may be registered on several BSCW servers, e.g. on your own server in your company and on a public BSCW server. You may be registered under the same or different usernames.
Your Web browser may represent only one registered user at one and the same BSCW server at the same time; parallel work sessions of multiple registered users with one and the same browser at one BSCW server are not possible.
However, with most Web browsers it is possible to be logged in as user to several BSCW servers at the same time; parallel work sessions with different BSCW servers are thus possible.
Note: BSCW objects can be transferred between different servers to which you are logged on simultaneously only via your local computer as physical relay station: You store the data on your local system and then upload it to the other BSCW server. Your clipboards on the different servers are not connected to each other, even if they are represented by identical icons.
