Buzz, I fundamentally disagree with you about whether allowing unfettered access to cleric spells is unbalancing. Here's how I see it: the cleric (already probably the strongest class) has a variety of spells in the PHB, some of which are strong and some of which are weak, and which have a certain cross-section of utility. By freely adding any new cleric spell that is published, you allow the player an unlimited ability to increase the utility of their spell selection; they can still do all the stuff they could before, but now they have a whole lot more things that they can do, and there's no tradeoff or cost for that additional flexibility and power. That's a real concern for me.
Okay, I think this is what Rystil was getting at (as he says upthread), and clarifies the issue for me.
I'm still not sure I'd change my stance, though, because there's still the issue of their daily spell limits. Even with a ridiculously high Wis, a cleric still won't have more than 7-8 spells of a given level prepared, 5 if we're talking the higher levels. The question is, if a savvy player can already cherry-pick the 5-6 PHB spells per level that totally rawk, are you really throwing things out of whack if some of those spells now happen to come from another book?
I mean, just looking at the PHB, there are a bunch of spells, but only a small percentage of them are worth preparing on a regular basis. Even adding in a tome like SpC, are you really dramatically changing the landscape? This being D&D, a good chunk of those spells are never going to get used, while a tiny chunk are going to get used all the time.
Ergo, it seems to me like unrestricted access and one-for-one swap basically wash. So, I err on the option that invovles less work and (IMO) more fun: do whatever you want, but be willing to compromise if the game starts to break.

There's a second reason too, truth be told: allowing unlimited access to spells can create a quagmire of indecision come spell preparation time.
This I can agree with. Ideally though, the player should be learning the good and bad choices as they go, or else realize, "Hey, I have no aptitiude for sifting through all of this." Unfortunately, we don't live in an ideal world.
