Subject: Drb and PStore behaviour

I'm doing a remote database object so i can do:

result = database.find do |record|
    record[:name] == "john"
end

in the server object i have something like:

class Foo
     include DRb::DRbUndumped

     def find(&block)
             result = nil
             @store.transaction do
                     result = @store[:records].find_all do |record| 
          
                              yield(record)
                     end
             end
             return result
     end
end

well, the problem is yielding that block. All the database is 
"cloned/copied" (?) over the network when doing the find. I don't want 
to copy all that data, just return the found records.

I tried adding DRb::DRbUndumped to class PStore, but the same result.
The database size is about 3 MB.

Do you know how to solve this problem?
