Greetings from day two of SEARCC 2005 in Sydney. Nortel demonstrated their Multimedia Communication Server (MCS) for combining voice (phone), video and Internet applications. This is a bit like the Access Grid applied to business. You could do much the same yourself using the Asterisk Open Source PABX software and web scripts, but not everyone likes DIY development.
Nortel were using a large plasma screen to demonstrate the user interface. It occurred to me that the big screen might be useful for a team of people working closely together, such as in an emergency center. The group could look at the big screen to see who is logged in and available to be contacted.
