certain methods are treated specially by drb.  it was a mistake for rails to
override Object#id for exatly this kind of scenario - many peice of code
require it.

you need to do something like

class << ActiveRecord
   alias "id__", "id"
end

and then use this method.

you are calling Object#id/object_id - no ActiveRecord#id - check out the drb
source to see why.
