Inter-VM communication

[Luis Alfredo Perez]

Is there a way of interchanging data between 2 objects running in diferent VM?
I know I can create a pipe and stream the data with it, but I'm just curious about that ...
Thanks in advance!

Lots of ways to do this....
One way I've done this is using sockets. One VM can be the "server" and create a ServerSocket on some port. Then the other VM can connect to that using a Socket. You then get I/O streams to talk on.
Sending serialized Objects over the streams makes a pretty easy "protocol".
If both VMs are peers, then you have to come up with some kind of agreement about which is the server (first one up, probably).
