There is a brief description of a paper which appeared in Distributed Computing Magazine recently called : "Licensing and Metering" by Julia Miller and Alex Kotopoulis.
It covers several aspects of Security and may talk a little bit about our product Object/LM. If not there is info about that on our web pages. The full text of the article is available at: http://www.distributedcomputing.com.
It is titled: "CORBAsec: Securing Distributed Systems: Find out what CORBAsec has to offer for security-aware applications."
