I'm working on a PoW hashing function called RandMemoHash (http://bitslog.wordpress.com/2013/12/31/strict-memory-hard-hash-functions/) that may serve your needs.
Also I'm preparing a new password hashing / PoW function called SplashHash that is as fast as scrypt, but provides higher memory hardness, soon to be published.
Topic: ASIC-resistant hashing for altcoins (Read 773 times)
I think Quarkcoin already does something like this (switcheng algorithms) for quite some time now.
Had an idea this morning, searched and found someone else already thought of it: http://bitcoin.stackexchange.com/questions/18633/could-an-algorithm-be-made-asic-resistant-by-simply-adding-deterministic-permuta
Is anyone working implementing this idea in an altcoin already? Basically switching the hashing algorithm per-block (or maybe per-reward-halving-block) and making the new algorithm functionally dependent on the hash of the previous block. It seems that if implemented correctly it could make it substantially harder to develop an ASIC for such a scheme.
