In my mind, the real difficulty comes from not the costs but the exotic and 
diverse nature of hardware. This might even more conceivably link up with the 
"grid computing" idea. If I had such a heterogeneous network, and I needed to 
make some high-perf. computation, could I simply submit it to a grid system 
that would automatically reconfigure the computation for optimal performance, 
etc.? I'm thinking something like a space vessel being able to take advantage 
of all general-purpose processors on-board and in sufficiently close 
proximity (like say a space station). The problem abstractly not too 
different from a university campus with a lot of motley computer labs and 
unpredictable network setups (ie. dynamic nodes, network topology, so forth).

Thus, I think it's more of a software problem. Can you really build "the" high 
performance platform that successfully and completely abstracts the 
OS/network/CPU? What would be needed for such a thing? (I'm not thinking 
'Java', that's slow, thank you) Such software is surely in line with Beowulf
