Creating two distributed Haskell processes to connect to each other

I looked at some simple tutorials for the "Cloud Haskell" distributed process and wondered if I could create a distributed process chat system. So for the first time I thought that I should just see if I can send messages between two instances of the same program.

But I have no idea how to make two different distributed process programs with each other. How should I do it? Can I use a distributed process for this or do I need to use somehing else at the "below" level?

Thanks for all the answers!
