Yes, and no. Yes you can create a cluster, no it won't help 90% of your
software go any faster. If you do a typical "beowulf", you'll need
MPI/PVM enabled software (few and far between). If you use something
like openMosix, which will allow you to have one "big SMP",
multi-threaded programs won't benifit only X programs that all need CPU
time. oM is kinda hard to explain, but very, very cool if you have
hardware it runs reliably on.

And a cheap switch is only like $30....
