Sharing Data between 2 applications

Question

Hi,
I thought it would be a very common problem to share data between 2 (let's say C#) applications on the same machine.
There are many solutions on the web, but I guess better solutions might exist.
I don't want solutions like: Remoting, Piping, Sockets, Data files, Clip Board or Databases.
I want an asynchronous way of sharing data without using the file system (files or database).
The best technique I've seen so far is MSMQ.
Are there any better ways for doing that?
Thanks in advance
