I have done a couple of tests like those in the appendix, and it seems 
that the nodes can communicate. I can even start a ring and execute e.g. 
hostname on two nodes via mpiexec if I start the mpds on the nodes 
separately by hand, the one on the second node as a client to the one on 
the first. Nonetheless, mpdboot specifically does not work.
Any ideas?
