Hi all:

I was thinking about this question all weekend. It’s possible to have  
shared memory or objets or repository of objets between servers??

Imagine this: I want that all servers (several) have same data (an  
array for example). If one server change a value, this value change for  
all servers, if another server add item, this item is added for all  
servers.

This could be interesting for cluster app, etc.

Any idea?

Drb could fit the bill:  
[http://www.ruby-doc.org/stdlib/libdoc/drb/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/drb/rdoc/index.html)

It’s in in the standard lib.

you want a tuplespace. it’s part of drb, which ships with ruby.
