Ruby IPC: messaging, blackboard, etc.?

I am looking for Ruby crossplatform local and network IPC: messaging,
blackboard, etc. It would be great to find a survey of existing projects
in this area.
Things I am most interested in:
1) Distributed blackboard or any other publish/subscribe mechanism that
scales well with new nodes comming into play
2) Messaging system that will allow address messages to
thread@process.host

Thanks!
Dima

I think your first step would be to look into drb (distributed ruby)
which comes with ruby.

#1 is a request for Rinda's Tuplespace built on DRb and also comes
with Ruby. The Ruby Cookbook shows example usage for this.

I didn't understand #2.

By 2) I mean a messaging framework where addressable unit is a thread.
In other words, in such a system a following scenario would be possible:

Thread_X @ Process_A @ Host_N <--- snd/rcv messages ---> Thread_Y @
Process_B @ Host_M
(Framework may provide peer registration and naming mechanisms (for all
parts of such address). For example, process name or PID used in native
OS and network host name (IP addr) may be quite naturally used. As for
threads, there may be an agreement on how their names are built (such as
natural numbers, logical names, etc.))
