In theory, because the class fully exists at runtime as a big stack of nodes 
(essentially the p-code of Ruby), one could "disassemble" those p-codes, and 
reconstitute classes as source. Then one could trivially mail these around. Ask 
if you'd like to do it that way and I'l set you up.

However, I can't help thinking your outer problem could use a re-think. Can you 
use DRb (Distributed Ruby), send handles to these objects out to the other 
hosts, and let them call your objects? or would that load the system the wrong way?
