 == Static Access Only on Users ==
 
-This is the simplest configuration of `fedd`, used to allow users of other testbeds to use resources from yours using pre-configured projects.  The layout assumes that for each [FeddAbout#GlobalIdentifiers:Three-levelName] three-level name] you are willing to allow to use your testbed, you have set up a project that already has proper keys installed.  Because no local projects or local users need to be modified, `fedd` does not need access to boss.

 A commented fedd.conf (installed in `/usr/local/etc/fedd.conf`) on `users.isi.deterlab.net` might look like this:

+== Dynamic Keying only on Boss ==
+
+In this case there is still one running `fedd`, but it runs on `boss`, where it can add keys to user accounts and change project permissions.  While projects and users need to be kept in sync, the user keys need not.  The changes here are largely in the allocation section of the global configuration.
+
+The configuration assumes that patched versions of `addpubkey` and `grantnodetype` have been installed as `taddpubkey` and `tgrantnodetype` in `/usr/testbed/sbin` as described in the [FeddDownload#AdditionalScripts installation section].

+== Dynamic Keying with Distributed Operation on Users and Boss ==
+
+In this case two `fedd`s are running.  The one on users accepts and evaluates access requests but calls out to the `fedd` on boss to do the manipulation of local testbed state.  Boss may choose to firewall all other hosts (except users) away from the fedd port, though the    `fedd` access controls will also protect access.  The situation looks like this:
