Recently I was on a Security Roundtable discussion around instant messaging. The SRT team on the podcast were: Larry Pesce of Pauldotcom, Martin McKeay of Network Security Blog and Podcast and myself. Our IM expert who appeared on short notice and for which we were all very grateful is Krishna Kurapati, CTO of Sipera Systems. Some real world, good stuff on IM security and support if you are interested. You can get the podcast here. Enjoy!
