Yes, some of the SNA software does sort of do what I mentioned. I am not much at good at drawing maps that i mentioned either (but I am looking at some tools now).

The best thing about this dynamic map is that as the year go by you won't have to draw it. There will tools from companies like Google that just plug in all your data (data they have and data would import). There are of course moral and privacy issues that bubble up here when it comes to the public domain. But for companies who by their own right own all of the information and activity among their employees (email, chat , corporate social networks like Newsgator Social Sites), it makes sense that this would be a great dynamic graph to utilize for increasing collaboration and innovation.
