Multiblend version 1.2 has been released. With this version, NFS is no longer required, so the usage has become a lot easier. There are now only two requirements left: be able to SSH to the nodes without password, and pack all required files into the .blend file. That should be easy!
If you're upgrading from previous versions, please note the configuration file format has changed a little bit. The path to 'scp' needs to be set, and instead of 'projectpath' the nodes now have a 'workdir' option. It should be fairly easy to get things going.
Go ahead and get Multiblend!
