Performance Instructions:

Each group/musician should point their browsers to:

http://nodescore.kiben.net:8889/1.html
http://nodescore.kiben.net:8889/2.html
http://nodescore.kiben.net:8889/3.html
http://nodescore.kiben.net:8889/4.html
http://nodescore.kiben.net:8889/5.html

where they can login into the server by entering their name and pressing enter at the "Login:" prompt

The conductor/director should load this page:
http://nodescore.kiben.net:8889/admin.html
where she is automatically logged in as "admin"

The login status of musicans can be monitored in the header of the embedded chat client.

Once everyone has logged in the director can begin the timer and commence sending instructions to the musicians using the button panel above.

There is a networked client server stopwatch system here which is optimised for mobile devices, might be a usefull generic tool for networked performances.
Server : http://nodescore.kiben.net:8889/nsws.html
Client : http://nodescore.kiben.net:8889/nswc.html
There is one control stopwatch (server) and can be as many client you please, the clients will all lock on to the time broadcast from the central server instance and there will be no drift between them all.
