This one has an outstanding bug. ${conf} is not as you would expect
'the value configured at the start of the config.xml' it is the
directory that contains the config.xml file.

The two virtualhost elements are simply combined. And should
eventually be split out. so we have:

I'd also like to see a lot of items removed from config.xml the whole
advanced section for example. There is no need for a user to tweak
these values and more chance they will break something. The items that
they may want JMSXUserID and BufferCompression(perhaps not) could be
factored in elsewhere. Perhaps per virtualhost or even per queue.
