Subject: Re: Inter-Process Messaging

Thanks for all the answers. I now have:

primitives:
  - TCPServer/TCPSocket
  - UNIXServer/UNIXSocket
  - IO.pipe
  - named pipes
  - shared memory (can't find low-level lib?)

libraries: (after some digging on rubyforge)
  - DRb
  - Event Machine
  - ActiveMessaging
  - Slave
  - BackgroundDRb
  - System V IPC
  - POSIXIPC (not released)
  - reliable-msg
  - MPI Ruby
  - stomp / stompserver / stompmessage
  - AP4R (Asynchronous Processing for Ruby)

Frankly I'm still not entirely clear on what are the advantages of each, 
both in terms of features and in terms of performance. I guess I'll just 
have to write some code to find out...
