Right, but if I distribute ruby onto a completely different machine the 
ruby files do not have to be present over there do they? Does it cache 
them on the other server or do everything over the wire?

I'm doing a ruby on rails project here. So, if it does everything over 
the wire, wouldn't it do the db calls over the wire as well since the db 
calls run through the ActiveRecord files?

Thanks for your help.
