It get's even more interesting to think about an overview having all (or
at least a lot of free or commercial) mom compared to each other in a
number of disciplins like architectures or features.

If it is possible I'd like to get a copy of your work.

Ok, I understood you right at the first view. You said it already:
clustering. This however, as I pointed out earlier, is not possible in a
straightforward way or an out-of-the-box-solution yet. One might indeed
find a way to bind two xmlBlaster together running on two different
physical nodes. I can not exclude this :-)

You're very welcome.
