I've tried several - 7777, 9876, even killed apache and ran on port 80 (as 
root).

Yes, I'm essentially running the same code you include here (very 
similar).  What I find is that I can run client and server on the same 
machine (localhost) but I cannot run client and server on different 
machines.

I even killed apache and then used port 80 (as root) 
because I know that I can get to the machine running apache from the 
other machines.  No luck,though.  When I use the Ruby server on port 80 I 
still get 'Connection Refused'.  I even tried the simple web server on 
page 478 of the Pickaxe book and I cannot get to it from a remote machine, 
but I can get to it on the same machine the server runs on.  It's quite 
mysterious, I don't understand what apache is doing differntly from my 
server (why can I get to port 80 from a remote machine when apache runs, 
but not when my druby server runs?).  I'm stumped.
