I need acid

It just occurred to me that the reaction that makes key lime pie doesn't actually depend on citrus, just on acidity. This means, hypothetically, one could make this kind of pie filling with things more interesting than lime or lemon juice. I need a sanity check on this idea, and some suggestions of delicious low-pH liquids.

Thoughts so far:
-- a high-quality flavored balsamic vinegar
-- grenadine syrup (except the sweetness might be too much)
-- various acidic fruit juices (less exciting)
The pH of lime juice varies but it tends to float between 2 and 2.5; possibly none of the things I've thought of would be acidic enough. I would appreciate any suggestions anyone has. Also, if this is a bad idea, or if you have tried something like it, please tell me.
