We should probably clarify "non-routable" by saying "non-publicly routable".
Routers have no concept of restricted ip ranges other than what is programed
into them.  As long as you are debugging from a place that "knows about"
your private ip's, there shouldn't be a problem.  At GE we cross privates to
go from public to public all the time.
