All you need is Improved Trip and it's more like-
"I trip you and get a free attack while you're prone."
"I get up."
"I trip you and get a free attack while you're prone again."
"I get up again."
Ad nauseum, it's really annoying.
That's actually not correct. Standing up draws an attack of opportunity, but it doesn't "interrupt" the act of getting up, even if you trip them successfully again. You're essentially tripping them "again" while they're still prone.
Think of it in terms of states:
1. Trip changes your state to prone.
2. Standing change your state from prone to standing.
3. The attack of opportunity to trip takes place before you complete the action to stand, so while you're prone, you are rendered prone again.
4. Your stand action resolves, and you are changed from prone to standing. The trip when you chose to stand up from prone did not change your state to one that invalidated your "stand up" action.
So the endless chaining of trips actually doesn't work by the rules as written.

That said, I'd like to see AoOs cleaned up too. I love the idea, and I like that they add some interesting decisions in combat (and that they keep every friggin orc on earth from just strolling by the fighter and squishing the wizard), but I feel for folks whose games are slowed down by it.
