Hi,

I am wondering if Acid-State (http://hackage.haskell.org/package/acid-state) can be used to share data between processes running in different address spaces?

For example, one demon system process (not thread!) periodically collects data from Web and stores it in a list. On regular intervals this process checkpoints the list to a disk file.

Another independent process randomly starts and reads this list from the checkpoint file.

Can this simple scenario be done with Acid-State? Any conflicts accessing checkpoint file from two system processes simultaneously?

What other Haskell libs can be used for such a task?

Thanks!
