Una Merge does real-time merging and has per user undo. And it can do lots of stuff that seems darcs-like, though I don't know enough about darcs to say for sure (e.g. moving a user's own edits after other edits). http://www.n-brain.net/una_merge.html Regards, John A.

] [1.1 ] If you work with a text editor like Microsoft Visual Studio (maybe also Eclipse, don't know), each text editor has its own undo/redo history. However, when you perform refactoring - like renaming a function - this becomes an undo/redo on multiple files together, so in a sense these changes are part of a global history. If you read this paper, you will find an undo system for a colloborative editor complete with a theory that looks like a primitive version of darcs patch theory (complete with the dreaded merge bug of darcs 1):

You will probably find these papers informative as well:
