fyi, I have added to the trunk an OpenOffice document with drawings representing HornetQ components (in doc/diagrams/widgets.odg)

There are drawings for:
* server
* acceptor
* connector
* address
* queue
* core bridge
* jms bridge
* divert
* journal

The idea is to use common images across our doc/example/blog.

As I rewrite the HA chapter, I'm using these widgets to draw the different HA mode (shared store vs replicated store) and configuration setting (live-backup pair)
