CareWeb Collaboratory -- WebCast for guided database navigation

A typical collaboratory scenario for school nursing involves the following steps:
- a child visits the nurse office and is inspected by the nurse
- nurse fills out assessment form for a given chief complaint
- nurse then contacts nurse practitioner for interactive diagnosis
- they establish audio-visual teleconf link using standard pervasivetechnologies (in the current demo, we used VIC/VAT)
- they use CareWeb WebCast for synchronized navigation: e.g. nurse isfirst in control and shows the most relevant pages to the practitioner;then practitioner takes over the control and ask additional questionse.g. when visiting child health history pages etc.
Session control in CareWeb is implemented by a session identifier('cookie'), passed between client and server session on each request.
In the WebCast mode, both nurse and practitioner acquire the commoncookie. The passive site polls the session database for news using theJavaScript timeout mechanism.
