***** To join INSNA, visit http://www.insna.org ***** Hello, In our project http://www.commetrix.de we do just such things. Functions, hierarchical levels etc. can be represented as colors and sizes. We also work on visualizing the actual evolvement of networks of virtual communication. On the website you can get an impression of the results, e.g. by selecting movies on the news column on the left hand side. Here, you can see some examples of the evolvement of Enron's email corpus. Another example can be seen in the JCMC paper: http://jcmc.indiana.edu/vol10/issue4/cho.html Maybe that tool is something for your project.
