Not directly related to your article Bill, but here are couple of practical questions: 1. What does Davis security offer that traditional packages like Cerberus do not? 2. Is Davis security designed in Jini plug-n-play style? In other words, will it be possible to say keep JERI features in Davis and integrate some other security package into Jini if one chooses to.

Many thanks,
