1. Support for Multiple Gridftp/Kerberos doors on the same host by dcache script
  Gerd has a good idea on how to implement it
  Gerd: Supporting multiple types of authentication mechanisms on the same port in the same door might be possible.
2. Distributed Log file management, tools and procedures for distributed log analysis for problem detection and root cause analysis.
   Use Remote Syslog, configure log4j. Or use a special tcp log4j appender, but it requires dcache to use xml log4j configuration files. 3rd option is to use JMS appender for log4j. 4th option is to use cells appender (might not scale). Log entries can now be augmented with ids that allow relate operations in all components in dCache with a primary activity by a door or SRM. We can build a web service that can allow to trace all calls or activities triggered by a particular transfer or client request. We could join CERN effort that performs End-To-End storage monitoring. Billing already partially implement these ideas, the new system should incorporate billing as one of its parts.
