Oops, this was meant for the list as well, so others have the full discussion.

Your wish is my command :)

Check out r1903, I just hadn't committed this.

I still need to commit cluster example files, but I'm swamped right
now, so here's one for reference:

"""Simple description of a distributed cluster"""

controller = dict(host='krein',
                  engine_port=None, # default is 10105
                  control_port=None,
                  )

engines = dict(krein=2,
               haar=1,
               )

'krein' and 'haar' are valid hostnames on my subnet, to which I have
paswordless ssh access activated.

This is still very rough, but have a look and complain loudly of any problems.

Yes, they can.  I'm prepping a little simple example of how to
organize a code for this, I'll try to commit it in the next few days.

We try :)
