Cool.

have a couple different versions of a Venue service; there is the docking

The identification/authentication part of it comes for free - you can
arrange to be given the authenticated DN of the client when the service
methods are invoked on your service implementation. Authorization at this
point is up to the application; my current stand is that the Venue gates
login entry based on some access list, and Venue components can use the
current-user list or some other list as their access ctl list.

The first part of that is the service docs I sent the other day; the
information in there with the venue interface from the design document will
get you rolling. Step by step recipe book doesn't exist yet.
