Yep..
Obviously, these are conceptual, not actual, examples
Personally I don't believe in the concept of ASIC-proof. Commercial ASICs maybe, but the real issue is not a commercial designer (as far as I'm concerned) but NSA. A commercial designer has a few million dollars worth of investment capacity with doubtful rewards so miners can be "ok" knowing that they won't deal with an ASIC implementation anytime soon. But an NSA contractor can get billions so that the NSA can stay ahead of the game. USA has a full-spectrum dominance strategy and that means no cost is too big in order to be ahead of the game.
If I were the NSA I would order an ASIC platform with modular design that you can fit like 20 different chips on it for every possible hash. So if a coin gets generated that has a combination of hashA, hashB...hashZ, then I place the corresponding asic-coprocessors on the modular board and I've just got myself an ASIC-raper for that coin.
Everything is balanced in the end of the day. Coins like bitcoin which have multiple asics mining for it by individuals are more safe from a 51% NSA control because they have the same tools at their disposal to counter it, but mining is virtually dead for cpu/gpu.
Scrypts may be GPU only for the time being but if NSA tomorrow reveals an ASIC+ram combo that rapes scrypt, then scrypt will be in trouble until the ordinary miners can get their hands on similar equipment.
Complicated coins with like 10 hashes are much more mining-resistant for commercial asic solutions but at the same time gives the "agencies" a far larger headstart due to their budget to create custom implementations that the private sector won't have for years.
