You guys all misunderstand me, I think.

I am aware of the fact that bitcoin ASICs are a pure hardware implementation of something similar to this pseudocode (only in transistor logic that can't be intercepted anywhere):

while(nonce <= 0xFFFFFFFF){
 if (SHA256(SHA256(hex2bin(Header..0x00000000..nonce))) < target) return nonce;
 ++nonce;}

I am also aware that this particular series of computational steps is really only useful for performing this specific proof of work.

What I am suggesting is that someone will eventually devise a way to design a particular service or product that specifically uses the bitcoin-proof-of-work algorithm, in order to monetize the abundance of no-longer profitable ASIC devices that are now taking up space but people will be unwilling to get rid of due to how much they originally cost.

We already see this with SHA256 Alt coins, which I'm certain will be popping up in increasingly ridiculous numbers very soon.

Think out of the box a little bit.  Let's DESIGN something that can use this particular hardware function loop as-is.

We can use them to collectively find SHA256 collisions. Or as a living proof that SHA256 is safe.
But the economics of this is failed:  If we ever find one collision, the BTC/USD price could drop and many ASIC owners are long BTC.

I think there there will soon be a considerable amount of money to be made by someone who designs a service/system or what have you that is specifically meant to be used with ASICs microwave ovens that no longer make sense to mine cook with.

Could block erupters microwave ovens be used to encrypt / decrypt VOIP / SMS data somehow in a way that is meaningful?

I need to read more about this...

Do you see now how the things you are saying don't make a lot of sense?

I've personally (and recently) used microwave ovens to perform thin-film deposition of YBCO superconductor material onto a metal substrate via something called magnetron sputtering.

My point being: high temperature superconductors didn't exist when microwave ovens were invented.

Surely, a constant to a constant times a constant doesn't equal -1.
It does because i2 is -1, and amazingly it works the other way around too, so 2i is also -1. e is just 2 with some extra digits which we can ignore since we're dealing with integers here, so ei is -1 as well. And of course, π is an odd number, so -1 raised to the power of π is still -1. Ergo, e = -1. Q.E.D.

There are already thousands of threads about this.

The calculations required have to be hard to do, but easy to verify, and that instantly, securely and uniquely. There's hardly any real world application that would fit into this.

The only existing approach of calculating something somewhat "sensible" until now is being explored by Primecoin.

Back on-topic. Can the ASIC chip be removed from an ASIC-based bitcoin minor and be replaced with another ASIC chip to perform a different task.

contrary to popular belief, bitcoin calculations are not "complex."

"complex" is a relative term.  Many people find that anything beyond A+B is "complex".

Is it just my imagination or did somebody really prove that adding two of something equals nothing?

Forgive me if I'm off base here, but could some of the miners be used to generate vanity addresses?  I'm not certain if ASICs can still do this.  I'm just imagining a very interesting scenario where rich egomaniacs post bounties in excess of 25+ BTC, hoping to momentarily redirect the hashpower of the network. 

No, address generation uses completely different algorithms than what is used for mining.

If its an FPGA, it might also be good for:

- creating rainbow tables (pre-bruteforcing)
- monte-carlo-simulations
- some other bruteforcing stuff =)
 
If its an ASIC, as my pre-posters already mentioned, its mainly producting heat. And its not only SHA256, its SHA256 twice Wink

Microwave ovens can be used to destroy optical media very quickly. hehehe. Try it for about 2 seconds on a busted CD / DVD.

Love it. Such a brilliant yet simple way to put it.
Surely now there cant be any more 'confusion' re ASICs.

ASICs essentially can not be used for anything else. While they do use SHA256, they don't use it in such a way that you can do something else with the hardware.

I'm not certain what you mean by "Bitcoin hashing power".

Right now, the majority of bitcoin hashing power is supplied by ASIC.

In the past bitcoin hashing power was supplied by GPU chips, and before that it was supplied by CPU chips.

CPU chips and GPU chips have MANY other uses now that they aren't very useful for mining any longer.

If you are asking about ASIC, then you need to understand that ASIC is an acronym for Application Specific Integrated Chip

You should probably go learn what the word "specific" means if you are asking what else it can be used for.
