Building A Remote Cluster With Storm Linux?

b0nk3d asks: "Hi, I work at a computer lab and would like to set up a remote login cluster. I have 4 Pentium Pro and I'm running Storm Linux on them. Do you think it'd be efficient to do a load balancing schema or a process sharing cluster? Also are there any recommended distributed file systems that would work well with small 2-6 gig drives that these machines have so that I could create a virtual volume?"
