Yes, it's an inter-app communication thing.

It is a "GOTO" in disguise; your app send of a WM_MESSAGE and you're off hunting where that is consumed.
Sorry, but the messenger-idea is a solution is search of a problem; there's more efficient ways of inter-app communication, and they have been around for some time.
In the rare case where multiple machines need to communicate over the internet, I'd opt for my own sockets; even XMPP would be preferable to a "new" solution, as it limits my dependencies - there would be enough alternatives if the provider of the solution goes belly up.

I've been working on an app that uses SignalR. Do you think this would be a good way to handle inter-proc commincations?

I can't say, I haven't used it in a real scenario yet.
Their website however states;
ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy Windows is not a real-time OS. Meaning a library on IIS, piped through ASP.NET, utilizing something else on top of that, is not in my definition of "real time".

There seems to be a misunderstanding from Kevin here. The Messenger implementation of Laurent's is intended for communication inside a single application. It's not inter-app communication.

No, I get it. I've used it in a large scale app before. That's why I mentioned that I thought it could be hard to debug when to classes are firing messages back and forth. I'm just curious about how else this could be done in a simpler manner.

"Inside" the application? A real (desktop) application, or a "webby" or "phoney" app?
Delegates? How about an observer-pattern? Windows messages? Mutexes? Which of those is the library itself using? 
To put it in Garfield-terms; "what's in it for me?", what do I gain by adding the dependency to this library?

Disclaimer: Laurent is a friend of mine, so I might have some bias here.
Messenger/Mediator style communications are perfectly fine because they allow you to separate classes, sometimes over different assemblies, whereby you don't have to know where you're getting a message from, just that at some point, you might (or might not) receive a particular message. This is a perfectly valid way of decoupling classes. What you have to watch out for is something called message explosion, whereby you send everything that you can possibly think of over a messenger. If you're doing that, there should generally be other ways to do this.
BTW - if you're using MVVM Light, that's where the Messenger is.

I've used it before and I do like it. However I found that it leads to hard to debug code, especially if more than one process fires the same message concurrently. I've also seen apps that fire a message from class A to Class B, which then fires another message back to Class A. very hard to follow.
