Subject: Sending YAML over TCP

Hi,
     I'm trying to send simple data structures (hashes) to a daemon  
process one one machine from a client process via TCP.  I thought the  
best way to do this would be with XML or YAML.  Here's my simple server:

---
require 'socket'

server = TCPServer.new('127.0.0.1', 8080)

while (session = server.accept)
   session.puts session.gets
   session.close
end
---

Here's my simple client:

---
require 'socket'
require 'yaml'
require 'base64'

hash = { 'one'=>'1', 'two'=>'2'} # Send this to the server and get it  
back

client = TCPSocket.new('127.0.0.1', 8080)
client.puts Base64.encode64(h.to_yaml)
hash = YAML.load( Base64.decode64(client.gets) )
client.close
p hash
---

Obviously I don't know what I'm doing :-)  The above client/server  
works for my simple purposes, but I wanted to know if there's a  
better way to pass hashes from the client to the server and back.   
I'd prefer to stick with YAML (rather than XML) if possible.

Thanks,
Ryan
