I don't understand the usage scenario here.  You think someone's going 
to sit with a browser window open, watching for things to change on the 
calendar?  Isn't it more likely they'd want to be notified in some 
other way, like by an email telling them that there was a new request 
(for the company) or a new appointment (for the user)?
