What you want isn't possible at the moment AFAIK.

To utilize a two computer cluster you have two options

1. write the programs specifically to run on a cluster (using mpi for example).
2. Use ssi cluster system (single system image) such as mosix or kerrighed to
automatically load balance your cluster by automatically migrating processes.
None of these however can distribute a multi threaded program over different
nodes at the moment. You also have a memory bottleneck so a highly graphical
program probably won't run to smoothly when away (not to mention the issue of
load balancing gpu accelerated programs which is also not available at the

I did read about some system implemented in hardware over infiniband but I
can't recall the name at the moment and it's most probably not at the price
range that you intend.
