There are a number of solutions for this problem. Search for "multimaster"

Normal tcpip using python is not too hard to do either.

It's not clear from your question exactly what capability you require.

The easy case: ROS is a distributed system that supports topic sharing between computers out-of-the-box -- you simply need to use the ROS_MASTER_URI environment variable (see the Running ROS across multiple machines tutorial).

If you really need separate masters running on individual computers, follow the advice given by @ahendrix about "multimaster".
