That's more or less what I am doing, the server iterating over the
client list, dynamically created as well.  Only for a few hundred
clients, with invariably a few of them down, not yet installed, or
broken, the server just never seems to finish.

I'll have a look into the list partitioning logic in cfengine, to see
whether I can adapt it to something that works.

Corrolary question, does iterating over server lists work these days?
As in,
remote_hosts = ( host1:host2:host3 )

copy:
    /path/file dest=/var/cfengine/collect/$(remote_hosts)/file
server=$(remote_hosts)
