That's right. When a large number of nodes are invovled, you can choose
using AMI to (re)deploy your assemblies to improve the (re)deployment

TAO does support CORBA Messaging including AMI. To use AMI in your CIAO
components is by no means an easy task. The main reason is because when
you use AMI, (1) IDL compiler generates different CORBA skeleton code
for the IDL interfaces, based on which you must create your servants as
subclasses of these servants, and (2) the client side should also be
programmed differently. In CCM, all the above code is generated by CIDL
compiler for you, so it is very hard to manually replace the generated
code with your own AMI-based code. The right thing [TM] to do is to
enhance CIAO to support AMI natively, but it seems that we don't have
immediate plan for this yet as far as I know.
