Just finished reading all the posts here and I'm left with one question: What was the point of this thread again? I'm pretty new here and this is not even the first time I've seen this subject posted in the last little while.

I can't see the point as well. It seems some people can't use search...

Exactly, and no one has ever denied the possibility or plausibility of such machines, just the practicality of the implementation of same. There's a ton of stuff that's 'possible' but not financially viable. For instance, I could go out and spend all of my cash and savings on lottery tickets and possibly win, and even have a better chance than if I never spent anything. That does not make it a financially viable decision though.

OF COURSE no hash is FPGA or even ASIC resistant. It's just impractical and costly with the current gen technology. There are several DYI and company projects working on SCRYPT FPGA right now, and sooner or later it will be available. The whole POINT of developing a new coins is that you do if on the premise of working and available technology. Hell, when bitcoin came out it was 'GPU Proof' until the first person realized how to do it, and do it well.

Yes, Litecoin ASICs do not exist yet, but are not harder (or  costlier) to build than any Bitcoin ASIC. It's just a different hashing algorithm!

Scrypt has different parameters than SHA256, but those obstacles should be easily tackled.

really this old arguement again.  scrypt is sha256.  scrypt does a salsa20 8 times mix backwards and forwards, it makes the lookup tables difficult to predict.  you need to load it all into memory to hash it.  it requires a lot of on die memory to load the tables into.  there are no fpga boards on the market that have that much on die ram.  it would cost a fortune to develop.  with most scrypt coins having low value and low liquidity there is not incentive for an investor to deploy the several million it would take to build an fpga or asic just so that can make a few hundred grand.  they woould be competing with GPUs manufacturers which have already invented the wheel.

correction: there are no asic baords with memory enough for scrypt
fpga is right around the corner and the boards already exist

Ok and... I can't really see what you added to my previous post regarding that it was of course possible, just not practical at this current point to warrant anyone with serious funds putting a significant financial investment into.
