Small nit... PowerMac G4's and G5's still have a strong following. There's a lot of activity on Debian's PowerPC list. The G4's and G5's provide Altivec acceleration and the old gcc compiler even accepts -mcpu=power4. ChaCha is a simple algorithm that benefits from Altivec, even when you manage the 64-bit additions/carries in a 32x4 vector arrangement.
