I have noticed that others tend to personalise the string, often removing that version number. Would it be possible to append your personalisation to the version rather than replace it? From a trouble-shooting point of view, knowing that two routers connected by a circuit are either same version or vastly different often helps.

Way cool. And RSX even supports it. That was nice!
