(Flaiming sword - no Te req)
Well, then I look forward to someone answering the question that I've posed several times already, but remains conveniently ignored each time:
What is the difference, Hermetically, between 1) a stinky CreoAurum effect (or fog cloud, or whatever) cast around a person, and 2) the identical stinky CreoAurum effect that follows a person around?
Without Rego, how does it (or any of these spells) follow anything, or move at all?
As for the other spells, canon or otherwise, the rules state that Rego can change the location of an object - but don't give any automatic connection to a moving reference point, like a person, sword or other object. "A spell that allows the caster to control the effect only permits that control as long as the caster is within range." Not "within range" of the person or object, but of the caster.
I'm not saying I don't like these spells, I'm not saying I don't allow them - I'm saying that we're all winking at the lack of a clear explanation in Hermetic terms.
Hey - you're right, I was! (Wow, a year later...) But it was not so much a "debate" as a common confusion. (see below)
And on that note, I was dismissive to Saxonous, and I formally apologize for that - sorry, Sax, my bad. 
But in order to claim to "understand" the rules, one has to understand (among other things) that a Target and a target are not the same thing*, nor intended to be by the editors, and that confusion is second only to the use of the word "Level" in another RPG that will not be named here. It's understandable and common, but I was talking about only one, and Saxonous was confusing both indiscriminately.
With Respect to Xavi's superior long-term memory that jogged my own, here is a thread that might prove useful in this matter:
(* There are actually, at least, 4 distinct and separate uses of the term "target/Target", but atm I am only referring to "the T/target of a spell".)
