My perspective: the dodge feat, house-ruled, would not be near the power of a +2 to Dex.
Moreover, it's probably about the same power as Weapon Focus, though due to Weapon Focus applying only to a single weapon, an argument could be made for the two being equal in power
before the houserule.

Now, by the RAW, I believe it's meant to be "one time per round", myself.
Well, the player would argue that, RAW, it's not "one time per round" and the text clear states "on any action." That's
horrible wording, if you ask me, but I do agree with you (and Chris Lindsay) that it's
supposed to be "once per round."
Though, considering a lot of people make the houserule that Dodge is a flat +1 Dodge bonus to AC, the "on any action" interpretation a) isn't more powerful and b) has
some rules support.

I don't think they intended it for you to shift it all over the place in the course of your action. Otherwise, you could run by a whole LINE of six or more defenders, triggering op-attacks, and have it apply to every single one, making the reason for it applying to one attacker at a time irrelevant.
This partially begs the question "what is an action"? There are three interpretations that I can think of.
Certainly, the step of every run is an action, as is blinking or breathing, and you could argue that you could trigger a line of op-attacks, but that's not an "action" in the usual rules sense.
Which is significant because AoOs aren't "actions" they're "attacks." If the character made a move action to trigger AoOs from the line of attackers and then ended with a standard action to attack his intended target (assuming he made it by that terrible line!), you could argue that he only made two actions, and thusly only had the opportunity to change his Dodge-buddy twice. (Though, admittedly, there isn't a specified limit to how many times you can change your Dodge-buddy on any action... it seems reasonable to say that once is a default.)
You could also argue that "on any action" would refer to an initiative count. As in, "Roy just moved. It's Belkar's action now." In which case a Dodger could change his Dodge-buddy once during Roy's turn and once during Belkar's turn. Which you may argue with, but look at the Dodge feat again--it starts "During your action..." which is normally read (or understood) as "During your
turn..." Wow. I'm starting to think once per round sounds like a
houserule.
Again, all of these interpretations are
still weaker than the common houserule (which I don't use, BTW), and the only balance problem comes into play when you look at a feat that says, "Whenever you are hit by an attack by an opponent which you have chosen for your Dodge bonus..." or "Whenever an opponent which you have chosen for your Dodge bonus misses you with an attack..." (there are tactical feats to this effect, I believe).
