Last weekend there was a special session on Homotopical Algebra with Applications to Mathematical Physics at eh AMS meeting in Raleigh. I was unable to attend in person but Tom Lada set up via Skype and opportunity for me to participate. I strongly encourage this technology for virtual attendance at such meetings or informal equivalents. Slides from the session are becoming available at http://www4.ncsu.edu/~lada/NCSU%20special%20session.htm jim
