Arcana Evolved Sprytes have some oddball rules to make it work. They get the tiny bonuses, but only a +2 Dex and -2 Str. They have to use correctly sized weapons, but still take up a five-foot square and threaten the squares around them.
Their base speed is 10', but they get some flight. If you take the Spryte class levels, you get another +2 Dex, +1 spellcasting level, and a few other tricks, as well as better flight manuverability.
---------------------
Regardless of that solution -- and they're relatively balanced, in my experience -- tiny PCs have lots of problems and advantages. The biggest being, as others have noted, that they're really hard to find and can do massive damage with anything BUT a weapon in hand.
Spellcasters get a lot of upsides with no downsides and rogues will be nigh-invisible with that extra bonus to their checks.
I wouldn't really recommend it without using some kind of workaround like the AE system.
