I would say you have 2 options:

- 1 cluster with node attributes and these dummy resources I had
described previously in the thread. (Unless
  anybody has a better idea how to tackle this).
- 2 small clusters and use booth

Which one is better depends e.g. on where your servers are located -
timing/reliability issues with certain network connections
between them?
Bringing up the booth infrastructure is of course an issue as well...
