I am setting up a linux-based cluster, it's able to use local and remote machines... So if anyone's interested in being a part of the cluster, let me know, and I'll give you specifics.
Basically, the way the WAN cluster will work, is anyone participating will be able to use the available cluster resources. As of now, I am going to use 2 of my local machines to add to the cluster, and anyone in the WAN cluster would had access to those resources, as well as resources from other participating machines.
The way it works, processes can be distributed to other machines on the cluster from your machine (and TO your machine, when resources allow)...
Post here if you're interested, I'll get back to you asap.
