Yes, in the testsuite we do the same all the time.

You can set any environment with args which configure the embedded 
xmlBlaster server, e.g.
on which port CORBA listens etc.
Try
  java org.xmlBlaster.Main -help
for a (not complete) list of properties.
All properties from command line or from xmlBlaster.properties you can 
specify with args.

Here you initialize a Global object with the args configuration.
Take another Global instance for another embedded server instance if 
desired.

You create an XmlBlasterAccess instance for every client instance.
You configure the client instances with separate Global instances, similar
to the above example.
XmlBlasterAccess will then connect to the embedded server
(see for example HelloWorld6.java on how to configure XmlBlasterAccess
hard coded)
