I would rule that as a "no" because I hate to do bookkeeping. I treat all effects as sticky when they trigger, so when Taunt goes from 0 to 1 I check and mark everyone who will get tagged. Then I check during upkeep to see who'll be affected and mark them for the round as well. This removes the need to do live ongoing checks for taunts, auras, etc. It keeps things flowing.
The only time I would check on the fly is when someone ends their movement within the taunt range, then I would rule that they have to adjust their future use of runes. Simply passing through wouldn't elicit the effect.
The same can be said for alkas. I won't apply the alka bead effects until then end of the movement. Applying each bead in succession will slow down the game too much imho.
But it's a game, and everyone has their threshold of abstraction. Some may say they'd rather sacrifice some abstraction to keep a certain degree of "realism". Simply go with that works for you and your group, and have FUN!
