Communication between JVMTI agent and separate JVM

First off i apologize as this is somewhat answered already here, but I think my situation is a bit different.

How to communicate with jvmti agent attached on a running JVM

My main question is... I am wondering if there are anyways using the JNI or other libraries to communicate between a JVMTI Native Agent and a completely separate JVM.

Here is a small illustration

enter image description here

So whats happening here. The JVM on the left is loaded with a native agent. Just for discussion sake let's assume I have no access to the source code of this java application. So instead I use the Java Native Agent to garner information from the objects.

Now I want to transfer the information to the JVM on the right. Represented by the broken link. Ideally i'd like to call a method on JVM2, have the Native Agent load information from JVM1 and then return it to JVM2.

I'm pretty sure I can do this with sockets, but I was just wondering if I had any other options here such as using JNI and registering native agents or something like mentioned in the previous answer.

So since nobody replied, I'll just post here that I'm gonna use Sockets.

Here is an example I used.

sending doubles via TCP between Boost ASIO server and Java client
