asterisk users - Jul 2011 - Is there a protocol to be used to communicate between different Asterisk Boxes to distribute load and tasks

Really I am thinking in something and I donot know if it can be used or not:

Is it possible to use the Database (to be located in a server) so whenever the
agent is login via any server, this will be logged in the database, so all the
queues in all the boxes can check with this database  to see if the agent is
logged in and if it is available or not.

Is it possible to be like this?

About DUNDi, really I am not able to understand how I can use DUNDi to route the
call for the queue that has available agent if no queue has available agent,
then to queue in specific queue? I am assuming the queues are existed in more
than a box (queue 1 in box 1 and queue 2 in box 2, ... etc).

Really I am in a need for help in this subject.

Bilal
