drb-1.2 has just been released.
  ->  http://www2a.biglobe.ne.jp/~seki/ruby/drb-1.2.tar.gz

* feature:
  o Access Control List (optional)
  o Remote Iterator behaves properly. (break, next, redo, retry...)

* problem:
  o No English document, sorry.


* Remote Iterator sample:

# array server
require 'drb/drb'

DRb.start_service('druby://localhost:9001', [1, 2, "III", 4, "five", 6])
DRb.thread.join


# array client
require 'drb/drb'

DRb.start_service()
ary = DRbObject.new(nil, 'druby://localhost:9001')

p ary				
p ary.collect { |x| x+x }	# Note
ary.each do |x|
  break if x == "five"
  next if x.kind_of? String
  p x
end	 



#Note:
Proc object '{|x| x+x}' is called back by server.
Marshal can't dump Proc object. Client sends "collect" message with
"{|x| x+x}"'s reference object (DRbObject) to server, by drb mechanism.
Server calls this reference back, in collect method.
