Euro-Office codebase will, obviously, not diverge significantly from the original product. If they planned fundamental changes, they would have started from scratch because taking over a huge project and rewriting its basis is an ever more daunting undertaking.
As such, any future patches to both codebases should be trivial to copy from one another, which essentially makes it collaboration.
