Mixed Language Environments

Thanks for the reply Martin.

I was experimenting with simple types (integers, strings) and had no  
problem accessing the values stored by a Java client from a Ruby  
client, but not vice versa.  The Java client could see the keys, but  
not decode the data.  Not sure if the Java client is intended to be  
used in mixed language environments, however.
