Christian, there are good semi-crypto hash functions that don't leak as bad as Python's own modified FNV hash, without going all the way to HMAC.

SipHash has very good collision resistance and doesn't leak anything:

(notice: they distribute a python program to recover python's seed)

It's obviously slower than Python's FNV, but it's hard to beat a sum+multiplication per character.
