Elsecomment I explained this more...

It is as low risk as trying to use Windows and Microsoft Word with a keyboard and mouse mirrored to a Linux machine running Open Office and expecting the same results.

You can't run the two systems side by side - different screens, different keyboard entry... and some of the keyboard entry can't touch the other system.

And this is assuming you can put a dry path into the production system. If the answer is "no", then you're putting a dev environment into a production environment... and that's certainly a "no".

We had test environments and we had a lab were we had two rows of systems where the two systems sat back to back and each row was hooked up to a different test store (not feasible in a production store environment).
