Don't think about singletons, think about a service. You can establish a service on one JVM and communicate with it via JMS from the other machine.

Everything is possible, but is it worth it? Most likely there is another approach to solve your problem. If you wish to communicate between application using singleton-like object, try JMS, web-services, RMI, shared file, anything ...

EJB 3.1 supports singleton EJB 's. I think this is the best way where you can centrally deploy this.
