I do however need access to the bean manager to use, which I can get from the (Flat)Deployment attachment. I do see some issues down the line if a deployment has several bean managers, but want to get something up and running before digging into that.

This is the name under which BootstrapBean is registered in MC:
* String bootstrapName = DeployersUtils.getBootstrapBeanName(unit);

Yes.
I would rather change BMDDeployer than go down that ugly path you describe in your 2nd post. :-)

e.g.
Have a list of ControllerContext creators in BMDDeployer,
short circuit-ing on 1st return context instance; by default creating KCC.

This is the magic that does it:

  |       install.addParameterMetaData(Iterable.class.getName(), bootstrap.createInject(ejbServicesValue.getUnderlyingValue(), "ejbContainerNames"));
  |       install.addParameterMetaData(String.class.getName(), "Start");
  |       install.addParameterMetaData(String.class.getName(), "Start");

  |       else
