Just to note there's this thing already in RAA

  http://rubymine.org/raa/raa-history-Library_Utility.html#sysvipc

and the portion of docs touching shared memory issues

  http://deisui.bug.org/~ueno/ruby/sysvipc_doc.html#label:11

And here, I guess, is the quite portable shared memory library Markus was
discussing about

  http://www.engelschall.com/sw/mm/

I believe some portion of it has been used as a basis when building
Apache.

I'm quite sure there're many uses for mm extension. What it comes to DRb
I'm sure there are other ways too, while shared memory is without doubt
one quite strong contender.
