  That should be just proxying...

  The detail file doesn't handle Access-Requests because they can't be delayed.  i.e. An Accounting-Request packet that's been sitting in a detail file for 2 hrs can still be sent to a home server.  An Access-Request packet can't be sent 2 hrs later, because the client has given up.

  There's also no way to get the responses back from the home server, through the detail file, and back to the client.

  So... a better question is what, exactly are the requirements, and why?

  As a short note... all of this will become trivial in v4 once that's done.  Proxying packets to multiple destinations, etc. will be a 5-line config, instead of "impossible" as it is today.
