Well, I guess Rijndael is "easier" to brute force in that it's faster than Twofish. But "easier" to brute force doesn't mean a whole lot; AES-192 is easier to brute force than AES-256, but both are so outside the realm of current-day computation than it doesn't really matter.

Just as a matter of interest, re: the new bitcoin boxes like the butterfly http://arstechnica.com/gadgets/2013/06/how-a-total-n00b-mine...

Do these put a different slant on the whole "current-day computation" angle? Not necessarily these machines, but isn't it feasible that custom hardware could be manufactured using current tech, that upsets the notion of AES brute force feasibility?

No. https://bitcointalk.org/index.php?topic=121264.0
