You may be able to do what you want by defining your own classpath
mechanism. The website has not been updated yet but if you look at
loom/site/xdocs/reference/classman.xml it should give you a basic overview
of the way to define the classpath.When defining the classpath you could
then define a classpath entry using property expansions such as

<classloader name="Y" parent="X">
    <entry location="${myApp.jdbcDriver.location}"/>
</classloader>

Then when you start up Loom you sure you set the system property to correct
value using something like

export LOOM_OPTS=-DmyApp.jdbcDriver.location=/usr/local/java/myDriver.jar
loom.sh start

I think that should work. Give us a yell if something does not work as
expected.
