But that will always be a problem in a game where some items are just flat out better than others. Part of what I perceive as the problem with the current system is that the element of choice is already there before you even add in the limit on MID use. The choice is "do I use this item now or in the next encounter?". The current system adds layer of overall limits per day and can create a climate where players hoard item use.
Then the question is, why bother to get items with "useless" MIDs?
Players tend to hoard daily powers (class powers) because there could come this one encounter where they will need them; should I make those powers encounter powers, so that they will stop worrying/hoarding?
It's hard for me to say if this houserule is balanced. Players can nova with daily powers and then nova with daily items in the next encounter. That's the most obvious scenario I can see. I just don't know if that's going to be overly abusive.
The level of abuse depends on your players...

I like this much better. INT is what I came up with quickly, and could be a fun way to differentiate INT from DEX (dex gets the nice side benefit of initiative bonus). Your way does seem more fair though.
More fair, as I said.
